A rectangular prism and its dimensions are shown in the diagram.
6.5 in.
5 in.
7.5 in.
What is the total surface area of this prism in square inches?

237.5 square inches

Step-by-step explanation:

Total surface area  of rectangular prism  = 2 (lw+wh +hl)

, where l= length

w = width

h= height

Given:  A rectangular prism and its dimensions are.

6.5 in.  ,5 in.  ,7.5 in.

Then, the total surface area of this prism  = 2 (6.5×5 + 6.5 × 7.5 + 5×7.5)

= 2 (32.5+ 48.75 + 37.5)

= 2 (118.75)

= 237.5

Hence, the total surface area of this prism = 237.5 square inches

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
