What is the surface area of a rectangular prism with the following dimensions? length: 8 cm width: 13 cm height: 10.5 cm 63 cm2 1,092 cm2 2,184 cm2 649 cm2

Your answer would be 649cm2 given the dimensions

The solution: A=2(wl+hl+hw)=2·(13·8+10.5·8+10.5·13)=649cm²

Option D. 649 cm² is the correct option.

Step-by-step explanation:

Since surface area of a rectangular prism is calculated by the formula

Surface area = 2(length×width + width×height + length×height)

= 2(8×13 + 13×10.5 + 8×10.5)

= 2(104 + 136.5 + 84)

= 2(324.5)

= 649 cm²

Therefore, Option D. 649 cm² is the correct option.

the answer is 8/21
