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.

Front

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

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height), where Base Area is the area of the triangular base.

Front

If a rectangular prism has a length of 5 cm, width of 3 cm, and height of 4 cm, what is its surface area?

Back

Surface Area = 2(5*3 + 5*4 + 3*4) = 94 cm².

Front

What is the surface area of a rectangular prism with dimensions 10 cm x 5 cm x 2 cm?

Back

Surface Area = 2(10*5 + 10*2 + 5*2) = 140 cm².

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the surface area of a triangular prism with a base area of 20 cm², height of 10 cm, and perimeter of the base 18 cm?

Back

Surface Area = (20 x 2) + (18 x 10) = 76 cm².

Front

What is the surface area of a rectangular prism that is 22 cm long, 6 cm high, and 10 cm wide?

Back

Surface Area = 824 cm².

Front

If a triangular prism has a base with a height of 4 cm and a base length of 6 cm, what is the area of the base?

Back

Area = 1/2 * 6 * 4 = 12 cm².

Front

What is the surface area of a rectangular prism with a surface area of 34 cm²?

Back

Surface Area = 34 cm².

Front

What is the surface area of a rectangular prism with dimensions 5 mm x 3 mm x 2 mm?

Back

Surface Area = 62 mm².
