Answer:

35 cubic inches

Step-by-step explanation:

The volume of a pyramid is [tex]\frac{1}{3} bh[/tex], where b = base and h = height. To find the area of the base, we multiply 3 by 5 and then divided by 2.

  • 3 × 5 = 15
  • 15 ÷ 2 = 7.5

Next, we multiply 7.5 by 14.

  • 7.5 × 14
  • 105

Lastly, we divide by 3.

  • 105 ÷ 3
  • 35

Therefore, the answer is 35 cubic inches.
35 cubic inches is right
