Question

the length breadth and height of a cuboid are int he ratio 10:6:5 its total surface area is 1120sqcm find the area of its vertical faces​

Answer 1

Answer:

let ratios be 10x,6x and 5x

surface area of cuboid is 2(

lb+bh+hl)

Step-by-step explanation:

therefore, 2(60xsq.+30xsq.+50xsq.)=1120cm sq

2(140xsq.)=1120cm sq.

280 x sq. =1120cm sq.

x sq.=1120/280 sq.

x sq.=4 cm sq.

by cancelling the squares, x=4cm

therefore, 10x =40cm,6x=60cm,5x=50cm

hope this helps u stay blessed dear

Answer 2

Answer: let ratios be 10x,6x and 5x

surface area of cuboid is 2( lb+bh+hl)

Step-by-step explanation:

therefore, 2(60xsq.+30xsq.+50xsq.)=1120cm sq

2(140xsq.)=1120cm sq.

280 x sq. =1120cm sq.

x sq.=1120/280 sq.
