Question

The total surface area of a rectangular prism is___

• A. $2\left(lb\right)+2\left(bh\right)+2\left(lh\right)$
• B. $lbh$
• C. $2\left(lw\right)+2\left(bw\right)$
• D. $2(l+w)h$

Answer 1

The correct option is A $2\left(lb\right)+2\left(bh\right)+2\left(lh\right)$

Let,
Length of the rectnagular prism $=l$
Breadth of the rectnagular prism $=b$
Height of the rectnagular prism $=h$

The total surface area of a rectangular prism $=2\left(lb\right)+2\left(bh\right)+2\left(lh\right)$
