Surface Area

Front

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

Back

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

Front

What is a prism?

Back

A prism is a three-dimensional shape with two parallel, congruent bases and rectangular faces connecting them.

Front

How many faces does a triangular prism have?

Back

A triangular prism has 5 faces: 2 triangular bases and 3 rectangular lateral faces.

Front

What is the surface area of a cube with a side length of 4 cm?

Back

Surface Area = 6s² = 6(4 cm)² = 96 cm².

Front

What is the height of a rectangular brick with a length of 5 cm, width of 9 cm, and surface area of 650 cm²?

Back

Height = Surface Area / (2lw + 2lh + 2wh) = 20 cm.

Front

What is the surface area of a cylinder with a radius of 3 cm and height of 5 cm?

Back

Surface Area = 2πr(h + r) = 2π(3)(5 + 3) = 150.8 cm².

Front

What is the surface area of a triangular prism with a base area of 30 cm² and height of 10 cm?

Back

Surface Area = Base Area + Lateral Area = 30 cm² + (Perimeter of base * height).

Front

What is the perimeter of the base of a triangular prism if the sides are 5 cm, 6 cm, and 7 cm?

Back

Perimeter = 5 cm + 6 cm + 7 cm = 18 cm.

Front

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

Back

Lateral Surface Area = Perimeter of base × Height.

Front

What is the surface area of a rectangular prism with dimensions 2 cm x 3 cm x 4 cm?

Back

Surface Area = 2(2*3 + 2*4 + 3*4) = 52 cm².
