the door's hight is 5 m and the hight of father is 2x of sis son . His son's hieght is h.4 m . will they pass through the door ?

Answer»

Given:

L=5 m, B=4 m, H=3m

⇒AREA to be WHITE-washed = Area of cuboid − Area of base.

=2lh+2bh+2lb−lb

=2lh+2bh+lb

=[2×5×3+2×4×3+5×4]m2

=74m2

Cost of white washing PER m2 area = Rs.7.50

Cost of white washing 74m2 area=74×7.50

= Rs.555
