(i) Calculate the area of each face;
(ii) Calculate the total surface area of the cube,
(b) Calculate the volume of the cube in cubic centimetres.

I am confused can someone help

Answer 1

a) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.
