1.) Use the rectangular prism shown to answer questions a.) and b.)
a.) Find the surface area of the prism

Step-by-step explanation:

5 in, 3 in, 15 in

Referencing to width on most rectangular prisms, the smallest value is likely to be width. Which is crossed out to get from volume formula to surface area formula.

So from (5in)(3in)(15in) goes to (5in)(15in), multiplied, the surface area of the prism is 75

5+2x=a
