Answer:

84 cm³

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

V = 1/3Bh

where B is the area of the base.

The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...

A = 1/2bh

A = 1/2(8 cm)(7 cm) = 28 cm²

Then the volume of the triangular pyramid is ...

V = 1/3(28 cm²)(9 cm) = 84 cm³
