Question

if the dimension of a cuboid is 3 m 4 m and 10 m . then find its surface area

Answer 1

Surface area=2(lb+bh+lh)
=2(12+40+30)=2×82
=164 m^2

Answer 2

hey dear,

good morning friend.


given,

dimension of a cuboid = 3m × 4m × 10m

thus,

its length(l) = 3m

breadth (b) = 4m

and,height(h) = 10m

We know,surface area of cuboid = 2(lb+bh+hl)

= 2(12 + 40 + 30) m²

= 2(82)m²

=164m² Ans.




Thanks.
