Question

10. The dimensions of a cuboid are in the ratio 1:2:3 and its volume is 384 cu.m. Find its dimensions and surface area.​

Answer 1

volume of cuboid = l× b × h m^2. l= 4m.

Answer 2

Answer:

Volume of the cuboid=lbh=384 cu.m

⇒x×2x×3x=384

⇒6x

=384

⇒x

384

=64

⇒x=4 m

⇒length=l=x=4 m

Breadth=b=2x=2×4=8 m and height=h=3x=3×4=12 m

Thus, dimensions of the cuboid=4:8:12

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

=2(4×8+8×12+4×12)

=2(32+96+48)

=2×176=352 sq.m
