Answer:

=280

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!! :)

Answer:

  • 212 in²

Explanation:

Top and bottom:

  • 2(2 + 4)*4 = 48

Front and back:

  • 2(4*7 + 2*10) = 96

Left and right:

  • 10*4 + 4*7 = 68

Total surface area:

  • 48 + 96 + 68 = 212 in²
