What is surface area?

Back

The sum of the areas of all the surfaces (faces) of a 3D shape.

How do you calculate the surface area of a rectangular prism?

Back

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

What is the surface area of a rectangular prism with dimensions 5 m, 6 m, and 7 m?

Back

Surface Area = 2(5*6 + 5*7 + 6*7) = 2(30 + 35 + 42) = 2(107) = 214 m².

What is the surface area of a rectangular prism with dimensions 10 in, 12 in, and 14 in?

Back

Surface Area = 2(10*12 + 10*14 + 12*14) = 2(120 + 140 + 168) = 2(428) = 856 in².

What is the surface area of a rectangular prism with dimensions 3 cm, 4 cm, and 5 cm?

Back

Surface Area = 2(3*4 + 3*5 + 4*5) = 2(12 + 15 + 20) = 2(47) = 94 cm².

If the length of a rectangular prism is doubled, how does that affect the surface area?

Back

The surface area increases, as it depends on the dimensions of the prism.

What happens to the surface area if all dimensions of a rectangular prism are halved?

Back

The surface area decreases, specifically it becomes one-fourth of the original surface area.

What is the surface area of a rectangular prism with dimensions 8 cm, 9 cm, and 10 cm?

Back

Surface Area = 2(8*9 + 8*10 + 9*10) = 2(72 + 80 + 90) = 2(242) = 484 cm².
