Question

Which expression can be used to find the surface area of the following rectangular prism?

Answer 1

Answer:

option A

Step-by-step explanation:

Here we can see that , the dimensions of the prism ( cuboid ) is 3 × 5 × 6 . If a cuboid has dimensions of l × b × h , then its TSA is ,

⇒ TSA = 2(lb + bh + hl)

⇒ TSA = 2[ (3)(5)+(5)(6)+(6)(3) ]

⇒ TSA = 2 [ 15 + 30 + 18 ]

⇒ TSA = 15 + 15 + 30 + 30 + 18 + 18

Hence the option A is correct .

Hence option (A) is correct.
