The formula for volume of prism is base area × height.
The formula for the base area of this prism is base × height × 1/2 (it is a triangle)
basically, this is the equation:
(y × 6.4 × 1/2) × 12.6 = 693.504
y = 693.504 ÷ 6.4 ÷ 12.6 × 2
y = 17.2
I have taken the test and I can confirm that the answer is
B. 15 m, 20 m, and 25 m.
Have a fantastic day!
