So first we need the formula for a triangular prism

Which, since we have all of our number for base, and both heights, we can plug it intk our formula

When we calculate it, it comes out to be 1020 cubuc feet.
Answer:
3(1x-4) and (2x+1)-(6+6)
Step-by-step explanation:
Answer:
15 m.
Step-by-step 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.
