Answer 1

Surface area: 44 ft² or 44 square feet

Volume: 18 ft³ or 18 cubic feet

Explanation:

Volume:

V = whl

2 · 2 · 4.5

18

Surface area:

A = 2(wl + hl + hw)

2 · (2 · 4.5 + 2 · 4.5 + 2 · 2)

44

Answer 2

Solution given;

l=4.5ft

b=2ft

h=2ft

now

volume=l*b*h=4.5*2*2=18ft³

is a required volume.

Now

total surface area =2(lb+lh+bh)

=2(4.5*2+4.5*2+2*2)=44ft²

is a total surface area.
