Surface Area of Rectangular and Triangular Prisms

Front

What is a net in geometry?

Back

A net is a two-dimensional representation of a three-dimensional shape that can be folded to form the shape.

Front

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

Back

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

Front

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

Back

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

Front

What is the difference between total surface area and lateral surface area?

Back

Total surface area includes the area of the two bases, while lateral surface area does not.

Front

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

Back

Total Surface Area = bh + (s1 + s2 + s3)h, where b = base area, s1, s2, s3 = lengths of the triangular sides, h = height.

Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 × base × height.

Front

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

Back

Total Surface Area = 6 × (side length)² = 6 × 5² = 150 in².

Front

What is the total surface area of a cube with a side length of 13 inches?

Back

Total Surface Area = 6 × (13)² = 1014 in².

Front

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

Back

Lateral Surface Area = 2h(l + w) = 2 × 9(14 + 8) = 396 in².
