Question

The dimensions of a cuboid are in ratio of 1:2:3 and its total surface area 88m².Find the dimension of cuboid​

Answer 1

Step-by-step explanation:

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

let ,l=x

b=2x

h=3x

so,Total surface area=2(lb+bh+hl)

=2(2x²+6x²+,3x²)

88m² =22x²

88=22x²

88/22=x²=4

x²=4

x=2
