Answer:
Step-by-step explanation:
1.
The area of the base
= (7×6)÷2
= 21 m²
The volume of the prism
= 21×16
= 336 m³
2.
The area of the base
= (6×5.2)÷2
= 15.6 m²
The volume of the prism
= 15.6×9
= 140.4 m³
3.
The area of the base
= (5.7×7.6)÷2
= 21.66 m²
The volume of rhw prism
= 21.66×4.8
= 103.968 m³
= 104.0 m³ (rounded to the nearest tenth)
