Find the volume of a cube, one face of which has an area of 64 cm^2

Please help fast!

Answer 1

Area of the face of the cube which is in the shape of a square = 64.
64 = l^2
where l is the length of the edge of the cube.
l = 8 cm.
Now
volume of cube = l^3.
= (8)^3
= 512 cubic cm.

Answer 2

Area of one face = (side of cube)² = 64cm² .

Side of cube = √ 64cm² = 8cm .

Volume of cube = (8cm)³ = 512cm³ .
