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 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
Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter
2 inches by 3 inches looks like a rectangle.
Six inches
A rectangle does not have volume because it is 2 dimensional but it does have area which is length times width measured in square units.
9 inches
