Surface Area of Rectangular Prisms

Front

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

Back

The surface area (SA) of a rectangular prism is calculated using the formula: SA = 2(lw + lh + wh), where l = length, w = width, and h = height.

Front

What is the surface area of a cube with a side length of 5 cm?

Back

The surface area of a cube is calculated using the formula: SA = 6s². For a cube with side length 5 cm, SA = 6(5)² = 150 cm².

Front

If a rectangular prism has a length of 4 cm, width of 3 cm, and height of 2 cm, what is its surface area?

Back

Using the formula SA = 2(lw + lh + wh), the surface area is SA = 2(4*3 + 4*2 + 3*2) = 2(12 + 8 + 6) = 2(26) = 52 cm².

Front

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

Back

SA = 2(10*5 + 10*2 + 5*2) = 2(50 + 20 + 10) = 2(80) = 160 cm².

Front

How many square units of wrapping paper are needed to wrap a cube with a side length of 3 inches?

Back

SA = 6s². For a cube with side length 3 inches, SA = 6(3)² = 54 in².

Front

What is the surface area of a rectangular prism with a length of 6 cm, width of 4 cm, and height of 3 cm?

Back

SA = 2(6*4 + 6*3 + 4*3) = 2(24 + 18 + 12) = 2(54) = 108 cm².

Front

If the surface area of a rectangular prism is 300 cm² and the dimensions are 10 cm, 5 cm, and h, what is the height h?

Back

Using the formula SA = 2(lw + lh + wh), we can solve for h. 300 = 2(10*5 + 10*h + 5*h). Simplifying gives h = 3 cm.

Front

What is the surface area of a rectangular prism with dimensions 8 cm x 3 cm x 2 cm?

Back

SA = 2(8*3 + 8*2 + 3*2) = 2(24 + 16 + 6) = 2(46) = 92 cm².

Front

What is the surface area of a cube with a side length of 12 inches?

Back

SA = 6s². For a cube with side length 12 inches, SA = 6(12)² = 864 in².

Front

If a rectangular prism has a surface area of 200 cm² and a length of 10 cm and width of 5 cm, what is the height?

Back

Using the formula SA = 2(lw + lh + wh), we can solve for h. 200 = 2(10*5 + 10*h + 5*h). Simplifying gives h = 2 cm.
