Answer: the answer is 40 units squared
Step-by-step explanation:
the SA with a rectangular and square base is 2*s²+4*s*h
2*s²= the surface area
4*s*h= sideways (lateral)
s= 2 and h=4
so then plug it into "2*s²+4*s*h" and you get 2*2²+4*2*4
2*2²+4*2*4
2(4)+32
40
the answer you are looking for is B. 16
this is because if you round 7.89 to 8, and 21.25 to 21 then add 21 and 8
you would get 29
round 45.12 to 45
subtract 29 from 45
45 - 29
you would get 16
Write 77% as a decimal.
