Question

the ratio of the sides of a cuboid is 2:3:5. If the volumn of the cuboid is 21,870 cu m, find the surface area of the cuboid

Answer 1

hope it helps u. plz mark as brainliest

Answer 2

let the ratio of sides be X,
therefore.2x,3x,5x.
as we know.
volume of cubiod = 21870.
lbh = 21870.
(2x)(3x)(5x)=21870
30x³=21870
x³=729
X=9.
l=18
b=27
h=45
surface area=2(lb+bh+hl)
2((18)(27)+(27)(45)+(45)(18))
2×2115.
5022.
