Question

the Length breadth and the height of a cuboid are in the ratio 1 ratio 2 ratio 3 total surface area is 88 cm find the dimension​

Answer 1

Answer:

let be L=1x;B=2x;H=3x so because they are in ratio

Step-by-step explanation:

TSA of cuboide=2lb+bh+lh

               88cm^2= 2×(1x×2x+2x×3x+3x×1x)

               88cm^2=2(2x^2+6x^2+3x^2)

               88cm^2=2(11x^2)

                88cm^2=22x^2

                  88cm^2÷22=x^2

                     √4cm^2=x

                           x=2cm

L=1x=1×2=2cm

B=2x=2×2=4cm

H=3x=3×2=6cm
