What is the surface area of a rectangle prism with the width of 15 length of 10 and height of 8

700  

Step-by-step explanation:

Top + Bottom = 2(15 × 10) = 2 × 150 = 300

Front + Back = 2(15 ×   8) = 2 × 120 = 240

     Two ends = 2(10 ×   8) = 2 ×  80 =  160

                                    Surface area = 700

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
