Question

2 house's lenght is 12 m and 8 meter.if the height of those houses are 4 meter,what is the area of its floor?​

Answer 1

a house is in cuboid shape so

cuboid = 2(l×b) + 2(l×h) + 2(b×h)

length =12m,

breadth =8m,

height =4m.

cuboid area = 2(l×b) + 2(l×h) + 2(b×h)

= 2(12×8)+2(12×4)+2(8×4)

= 2(96)+2(48)+2(32)

=192+96+64

=352

therefore area of cuboid =352 square meter

I hope it will help you
