Answer:
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.
Surface area: 44 ft² or 44 square feet
Volume: 18 ft³ or 18 cubic feet
Step-by-step 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
