Question

A cuboid is 10m long and 5m high. Its surface area is 340m square. Find its breadth.

Answer 1

Answer: Breadth is equal to 8m

Step-by-step explanation:

Surface area of cuboid = 340m

length= 10m and height = 5m

Now,

surface area of cuboid = 2(lb+bh+lh)

340 = 2(10*b+5*b+10*5)

340/2 = 10b + 5b + 50

170-50 = 15 b

120/15 = b

8 = b

Therefore, the breadth of the cuboid is,b = 8m
