Question

figure 1 has a volume of 250 cubic meters. Figure 2 has a volume of 128 cubic meters. If figure 2 has a height of 12 meters, then the height of figure 1 is _____ meters.

Answer 1

15 meters

Explanation:

Answer 2

15 m.

Explanation:

If the figures are similar then the ratio of their heights is

∛128 / ∛250

= 0.8.

So 0.8 = 12/ h where h is the height of figure 1,

h = 12 / 0.8

= 15 m.
