Volume and Surface Area of Rectangular and Triangular Prisms

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

What is the formula for the volume of a rectangular prism?

Back

Volume = l × w × h, where l = length, w = width, h = height.

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = bh + l1h + l2h + l3h, where b = base, h = height of the triangle, l1, l2, l3 = lengths of the triangular sides.

Front

What is the formula for the volume of a triangular prism?

Back

Volume = (1/2) × b × h × L, where b = base of the triangle, h = height of the triangle, L = length of the prism.

What is the surface area of a rectangular prism with dimensions 5 cm, 8 cm, and 10 cm?

Back

Surface Area = 2(5*8 + 5*10 + 8*10) = 2(40 + 50 + 80) = 2(170) = 340 cm².
