Surface Area of Rectangular Prisms

The formula is $$SA = 2lw + 2lh + 2wh$$ , where l is length, w is width, and h is height.

'SA' stands for Surface Area.

The surface area is $$SA = 2(5)(4) + 2(5)(3) + 2(4)(3) = 70 cm^2$$ .

The surface area is $$SA = 2(10)(5) + 2(10)(2) + 2(5)(2) = 140 cm^2$$ .

You calculate it by using the formula $$SA = 2lw + 2lh + 2wh$$ .

The surface area is $$SA = 2(8)(3) + 2(8)(4) + 2(3)(4) = 96 cm^2$$ .

The unit of measurement for surface area is square units, such as cm², m², etc.

If the dimensions are doubled, the surface area increases by a factor of 4.

The surface area of a cube is $$SA = 6s^2$$ , so for a side length of 6 cm, $$SA = 6(6^2) = 216 cm^2$$ .

Surface area measures the total area of the prism's faces, while volume measures the space inside the prism.
