Hi
Just checking
The area of one face of a cube is 64cm squared
What it the total surface area of the cube?
DO we do 64 times 6 and the answer is 384 cm cubed?
Also it askes what is the volume
I do 64 cubed which is 262144 cm cubed ?
AM I right ?
yes the total surface area is 384 cm squared
to find the volume you do length x width x height so...
find the length of the side of the cube
you know each side is equal and the area of one face is 64... the square root of 64 is 8, so each side of the cube is 8 cm
therefore, 8x8x8 equals 512 cm cubed

Your area is correct but the volume is not.
The side of the cube is sqrt64 = 8 making ther volume 8x8x8 = 512cm cub.

very easy 512 cm cubed\
