Hint – In this question the length of all the edges are given so the length of a single edge can be taken out by assuming the length of one edge to be a variable x. Use the direct formula for volume of a cube which is $V = {x^3}{\text{ c}}{{\tex...
The surface area of a cube is determined by finding the area of one square by multiplying its length times its width, or by squaring the length of one side, and then multiplying that product by six for each one of the squares. Finding the volume of the cube requires multiplying its lengt...
