Answer:
=280
Step-by-step explanation:
Step 1:
find the surface areas of both the figures
area of 1rst:
length = 2
width =4
height = 10
surface area formula = 2(wl+wh+hl)
= 136
area of second
length = 4
width =4
height = 7
surface area formula = 2(wl+wh+hl) =
2·(4·4+7·4+7·4)=144
144 + 136 = 280
I hope this helps!! :)
