Question

A closed metal box in form of cuboid with dimensions 1.2mts,0.8mts 0.3 meters then area of metal sheet

Answer 1

Step-by-step explanation:

length of cuboid=1.2m

breadth=0.8m

height=0.3m

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

=2(1.2×0.8+0.8×0.3+0.3×1.2)

=2(0.96+0.24+0.36)

=2(1.56)

=3.12m²

Answer 2

Length of cuboid (l)=1.2 m

Breadth (b)=0.8 m

Height (h)=0.3 m

T.S.A = 2 (lb+bh+lh)

2 (0.96 + 0.24 + 0.36)

2 (1.56) = 3.12 m^2
