Answer 1

The volume of this prism is calculated by this equation:

V = (area of a triangle)(height)

So plugging in the numbers it looks something like this

V = (10 x 10.5 x 1/2)(8)

V = (105 x 1/2)(8)

V = (52.5)(8)

V = 420 mm^3

Answer 2

420mm^3

Explanation:

10mm×10.5mm=105mm

105mm×8mm=840mm^3

840mm^3÷2=420mm^3
