О 210 cubic inches

Answer 1

35 cubic inches is right

Answer 2

35 cubic inches

Explanation:

The volume of a pyramid is
`(1)/(3) bh`, 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.
