Answer: 375
Step-by-step explanation:
Since we are given the information that there are 250 bricks used to build a wall 20 feet high, the number of brick used per feet will be:
= 250/20
= 12.5 bricks per feet.
Therefore, the number of bricks that will be used to buld a wall that is 30 fet high will be:
= 12.5 × 30
= 375 bricks.
Therefore, 375 bricks would be used.
Answer:
495 in
Step-by-step explanation:
The formula for the volume of a triangular prism is V = 
· w · h · l, where w represents with, l represents length, and h represents height. Using this and plugging in the values, we can solve.
V = · 5 · 11 · 18
V = 2.5 · 11 · 18
V = 27.5 · 18
V = 495
hope this helps :)
