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.
