Question

the total surface area of a cuboid is 2350m square if its length is 15 m breadth is 20m find the volume​

Answer 1

Solution

total surface area

=2(lb+bh+hl)

now given that ..

2(lb+bh+hl)=2350

=>2(15*20+20*h+15*h)=2350

=>35h+300=1175

=>h=875/35

=>h=25 cm

therefore volume

=lbh

=(15×20×25)cm³

=7500 cm³

Hope this helps you.....
