Q&A for How to Find Cubic Feet

27.

Multiply 104 x 208 x 14 to find the answer.

The easiest way to do this is to multiply 30 x 16 x 15 and then divide that product by 1728 (the number of cubic inches in a cubic foot).

Square the diameter and multiply by pi to get the cross-sectional area of the log. Multiply that area by the length of the log. That gives you the volume in cubic inches. Divide by 1,728 to get the volume in cubic feet.

5000ftsq x 3ft in height is approximately 15000 cubic feet of gravel depending on exact interior volume.

Convert 6 inches to 1/2 foot and 1 inch to 1/12 foot. Then multiply 6 x 1/2 x 1/12.

Water displacement is by far the easiest method. Otherwise, you'll have to break the object into various segments mentally and calculate each of their volumes.

Measure the inside dimensions of the microwave, and multiply them together.

The formula is right, but the notations used in the illustrations are confusing. By 128^2 they don't mean 128 x 128, they mean 128 square inches. They should have written 128 in^2.

It depends on how deep the mulch is. For example, if it's spread two inches deep, it would cover 150 square feet (or a 15' by 10' rectangular area). If it's spread one inch deep, it would cover twice that much.

It depends on the shape of the pyramid's base. For example, with a square base, the volume formula is 1/3 of the product of the base area and the height, so it's 1/3 of the height multiplied by the square of the base's side. That means three times the volume equals the height multiplied by the square of the base's side. If the volume is 25, three times the volume is 75, and 75 could equal 3 x 5 x 5. So the height could be 3 inches, and each side of the base could be 5 inches. Other (more complicated) combinations are possible, but that's the easiest and most obvious.

Multiply 3000 by 4 to get the volume in cubic feet, then divide by 27 to get cubic yards.

If you're asking about the area of a square which has diagonals each ten feet long, each side has a length of (10 /√2) feet. Square that number to get the area: (10/√2)(10√2) = 100 / 2 = 50 square feet.

4 inches is 1/3 of a foot. So multiply the area by 1/3 to get the volume. (3,000)(1/3) = 1,000 cubic feet.

For a round log, 3.14 x square of radius x height. For a rectangle type log, length x breadth x height.

Each ball is ¼ foot in diameter. 16 of them will fit into a length of 4 feet. That means the box will hold 16 x 16 x 16 = 4,096 balls.

There are 43,560 square feet in an acre, so there are that many cubic feet in an acre-foot, defined as the volume of an acre of area to a depth of one foot.

Divide inches by 12 to get feet. Divide square inches by 144 to get square feet. Divide cubic inches by 1728 to get cubic feet.

The amount needed depends on the depth of mulch you plan to use. For example, if you were to use 4 inches (1/3 foot) of mulch, you'd want 33 cubic feet of mulch/straw. And 3 inches would be 25 cubic feet.

It will cost (5)(8)(1.5)($1.20) = $72.00.

The cubic footage is (14/12 ft)(12/12 ft)(70 ft) = 81.67 cu ft. The square footage depends on which dimension is the width. If the width is 14", the square footage is (14/12 ft)(70 ft) = 81.67 sq ft. If the width is 12", the square footage is (12/12 ft)(70 ft) = 70 sq ft.

(50 ft)(50 ft)(1/6 ft) = 416.67 cu ft.
