3. We need the area of the base and the height of the prism.
The height (10) is clearly provided, but we still need to find the base area.
Area of triangle = 1/2 × base × height
A = 1/2 × 6 × 10
A = 30
Now for the volume.
V = Bh
V = 30 × 10
V = 300 ft³
9. Same process as 3.
Area of triangle:
A = 1/2 × b × h
A = 1/2 × 6 × 4
A = 12
Volume:
V = B × h
V = 12 × 8
V = 96 cm³
