Question If a rectangular prism has a length of 3 1/2 in and a width of 9 in and a height of 3 1/2, what would the surface area be?

Answer: The surface area of this rectangular prism is 150.5 . Step-by-step explanation: The formula for finding the surface area of a rectangular prism is this : A=2(wl + hl + hw) l = 3.5, w = 9, h = 3.5 Now we substitute those values in and solve for A. A = 2 · ( 9 · 3.5 + 3.5 · 3.5 + 3.5 ·9) = 150.5 The surface area of this rectangular prism is 150.5 . Hope this helps, please mark brainliest. Have a great day! Log in to Reply

Answer:The surface area of this rectangular prism is 150.5 .

Step-by-step explanation:The formula for finding the surface area of a rectangular prism is this :

A=2(wl + hl + hw)

l = 3.5, w = 9, h = 3.5

Now we substitute those values in and solve for A.

A = 2 · ( 9 · 3.5 + 3.5 · 3.5 + 3.5 ·9) = 150.5

The surface area of this rectangular prism is 150.5 .
