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

Back

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

What is the significance of units in surface area calculations?

Back

Units in surface area calculations indicate the measurement of the area. For example, m² (square meters) or in² (square inches) show the size of the surface.

If a rectangular prism has a length of 5 m, width of 3 m, and height of 4 m, what is its surface area?

Back

Using the formula SA = 2lw + 2lh + 2wh, the surface area is SA = 2(5)(3) + 2(5)(4) + 2(3)(4) = 30 + 40 + 24 = 94 m².

What is the surface area of a rectangular prism with dimensions 2 in, 3 in, and 4 in?

Back

Using the formula SA = 2lw + 2lh + 2wh, the surface area is SA = 2(2)(3) + 2(2)(4) + 2(3)(4) = 12 + 16 + 24 = 52 in².

What is the relationship between the dimensions of a rectangular prism and its surface area?

Back

The surface area increases as the dimensions (length, width, height) of the rectangular prism increase. Changing any dimension affects the total surface area.

What is the surface area of a rectangular prism with a length of 10 ft, width of 5 ft, and height of 2 ft?

Back

Using the formula SA = 2lw + 2lh + 2wh, the surface area is SA = 2(10)(5) + 2(10)(2) + 2(5)(2) = 100 + 40 + 20 = 160 ft².

What is the surface area of a rectangular prism with dimensions 7 yd, 3 yd, and 2 yd?

Back

Using the formula SA = 2lw + 2lh + 2wh, the surface area is SA = 2(7)(3) + 2(7)(2) + 2(3)(2) = 42 + 28 + 12 = 82 yd².
