24 square inches !... and - it's spelled 'prism' !
The volume of a rectangle is 0. It is a 2-dimensional object and so has no volume.
A rectangle has no volume, it is a 2 dimensional object.
If a rectangle is 40 inches. the rectangle is 12 inches long then: 2 * 12 + 2 * width = 40 2 * width = 40 - 2*12 = 40 - 24 = 16 width = 16 / 2 = 8 So the width of the rectangle is 8.
A rectangle, being a 2-dimensional figure, cannot have a volume. The volume of a cuboid with sides of length 14.5 in, 21 in and 7.5 in is 14.5 * 21 * 7.5 = 2283.75 cubic inches ( = 1.32 cu ft, approx)
The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches
With great difficulty because a rectangle is a 2 dimensional shape which does not have a volume.
The area of a rectangle is calculated by multiplying its length by its width. For a rectangle measuring 2 inches by 1.5 inches, the area is 2 inches × 1.5 inches, which equals 3 square inches.
The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter
The volume of ANY solid with linear sides is calculated in the same way. LENGTH x WIDTH x DEPTH! volume of the liquid = (length X breadth X height) of the rectangular box length x width x height = volume 12 inches x 6 inches x 8 inches = 576 cubic inches
