Answer 1

If you triple the dimensions, the area becomes 3^2 as much
If you triple the dimensions, the volume becomes 3^3 as much

Answer 2

So you had a volume of 90. After you triple the dimensions, it will be 27 times as much.

Answer 3

V= LWH
new V = (3L)(3W)(3H) = 27 LWH

so 90*27= ??

Answer 4

It equals C
