Each face of a cube has an area of 400 cm2. what is the volume of the cube?

A cube is a square shape, so both sides ( length and width) of a face would be the same.

Find the length of the side by finding the square root of the area of the face:

Length = √400 = 20 cm.

Volume is Length x Width X height.

Volume = 20 x 20 x 20 = 8,000 cm^3

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
