Answer:
D)15+15+10+10+6+6
Step-by-step explanation:
the formula to find the SA of a rectangular prism is:
2(lw)+2(lh)+2(hw)
where
l=length
w=width
and
h=height
let's substitute the values,3,2,and 5 into the equation
2(5*3)+2(5*2)+2(3*2)=62
62 is the SA
from the options:
10+6=16
10+10+6+6=32
15+15+10+10+6=56
and
15+15+10+10+6+6=62
so option D is correct
