Question

find the sum with explanation

Answer 1

Answer:

Step-by-step explanation:

LET LENGTH=5X

LET BREADTH=2X

LET HEIGHT=3X

Surface area of cuboid= 2(lb+bh+hl)

2232=2(5x × 2x+ 2x × 3x+3x × 5x)

2232/2=(10x^2+6x^2+15x^2)

1116=31x^2

1116/31=x^2

36=x^2

Root 36=x

Therefore x=6

Now,

Length= 5×6=30

Breadth=2×6=12

Height=3×6=18
