Step-by-step explanation:
where is the question??
Answer:
136 ft^2
Step-by-step explanation:
Surface area = 2 [ (l*w) + (l*h) + (w*h) ]
= 2 [ (8*3) + (8*4) + (4*3) ]
= 136 ft^2
Well you have to find the lest common factor
8 times 6
6 times 8
They both equal 48 so it would be the vise versa
Divide the 30 from the 4 and you will get 7.5 and then divide the 45 from the 2 and you will get 22.5 and then times 7.5 by 9 and then you will get 67.5 and then do the same with the 22.5 with the 6 and then add them up and you will get 202.5
