Find the surface area and the volume of the right prism shown below.
sergiy2304 [10]

Answer:

Surface area: 592

Volume: 960

Step-by-step explanation:

First the surface area:

The formula for a rectangular prism is length times width, plus width times height, plus length times height times two

So,

lw= 12 times 10 = 120

wh= 10 times 8 = 80

lh = 12 times 8 = 96

(120 plus 80 plus 96) times 2 = 296 times 2 = 592

Surface area = 592

Second, volume:

Formula is length times width times height

12 times 10 times 8 = 120 times 8 = 960

Volume = 960 cubic cm.

Hope this helped. Sorry if I was wrong.
