If the edge length of a cube increases by 1 cm, its volume will increase by () cm;

If the edge length of a cube increases by 1 cm, its volume will increase by () cm;


The new volume is the cube of (3 + 1) = 64
The original volume is 3 cube = 27
So the volume increases by 64-27 = 37



The edge length of a cube is 1.1x10 & # 178; cm. Please calculate the surface area of the cube


S = 6 × (edge length × edge length)
6 x 1.1 x 10² x 1.1x10²
=7.26x10 4 power
