When finding unknown values, plug what you know into the formula and solve for what’s missing! Find the height of the triangular prism. V = Ah A = Area of the base h = height of the solid Atriangle = bh 1 2 1 2 Volume = ( bh)h h 1 2 189 = (7)h 7 m 6 m The volume of the prism is 189 m3.

The height of the prism is 9 meters!!
V = Ah A = Area of the base h = height of the solid Atriangle = bh 1 2 1 2 189 = (7)h Plug in what you know. 1 2 189 = (42)h 6(7) = 42 h 1 2 189 = 21h (42) = 21 7 m 9 = h Divide both sides by 21. 6 m The volume of the prism is 189 m3. The height of the prism is 9 meters!!

V = Ah A = Area of the base h = height of the solid The volume of the prism is 264 in3. The height is 22 in. Find the area of the base. Atriangle = bh 1 2 Don’t be mislead by how the solid sits. A triangle needs to be the base. If necessary, ROTATE IT!

The area of the triangular base is 12 inches!!
V = Ah A = Area of the base h = height of the solid The volume of the prism is 264 in3. The height is 22 in. Find the area of the base. Atriangle = bh 1 2 264 = A22 Plug in what you know. 22 12 = A Divide both sides by 22. The area of the triangular base is 12 inches!!
