Doing a paper, question shows two similar shapes, A and B

surface area of shape A : surface area of shape B = 3:4
Volume of shape A is 10cm^3
Work out volume of shape B correct to 3 sig. figs
The surface area of shape B is 4/3 times larger than the surface area of shape A.

Thus, the area scale factor is (4/3).

Square root (4/3) to get the length scale factor.

Cube this result and then multiply it by the volume of A.
