Question

the dimensions of a cuboid are in the ratio1:2:3 andits volume is 384 cu.m. find its dimensions and surface area​

Answer 1

Answer:

352 sq.m

please mark as brainliest.

Step-by-step explanation:

let

length=x

breadth=2x

height=3x

Volume=x×2x×3x=6x^3

so,

6x^3=384

x^3=64

x=64^1/3

x=4

so length=4,breadth=2×4=8,

height=3×4=12

surface area=2(4×8+8×12+12×4)

=2(32+96+48)

=2(176)

=352
