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

Front

How do you calculate the surface area of a cube?

Back

Surface Area = 6s², where s = length of a side.

Front

What is a net in geometry?

Back

A flat, 'unfolded' representation of a 3-D figure.

Front

If a cube has a side length of 5 inches, what is its surface area?

Back

Surface Area = 6(5)² = 150 in².

Front

What is lateral surface area?

Back

The area of the sides of a 3-D figure, excluding the top and bottom.

Front

How do you find the lateral surface area of a rectangular prism?

Back

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

Front

What is the surface area of a box that is 14 inches long, 8 inches wide, and 9 inches tall?

Back

Surface Area = 2(14*8 + 14*9 + 8*9) = 396 in².

Front

What is the surface area of a triangular prism with a base of 6 cm, height of 4 cm, and length of 10 cm?

Back

Surface Area = 6*4 + 10*4 + 10*6 = 148 cm².

Front

What is the surface area of a cube with a side length of 3 cm?

Back

Surface Area = 6(3)² = 54 cm².
