Question

The lateral surface area of a rectangular prism is___

• A. $2(l+b)h{\text{unit}}^2$
• B. $lbh{\text{unit}}^2$
• C. $2\left(lb\right)+2\left(bh\right)+2\left(lh\right){\text{unit}}^2$
• D. $(l+b)h{\text{unit}}^2$

Answer 1

The correct option is A $2(l+b)h{\text{unit}}^2$


The lateral surface area of rectangular prism is the product of perimeter of the base and the height of the prism.

Hence, the lateral surface area of a rectangular prism$=2(l+b)h{\text{unit}}^2$
