Question

Prameela painted the outer surface of a cabinet of measures 1m*2m*1.5m . Find the surface area she cover if she painted all except the bottom of the cabinet ?

Answer 1

length =1m.
breadth =2m
height =1.5m
The surface that prameela painted=TSA-(l×b)
2×(lb+bh+hl)-(l×b)
=2 (1×2 +2×1.5 +1.5×1) - (1×2)
=2 (2+3+1.5) - 2
=2 (6.5) - 2
=13 - 2
=11.
The area she painted was 11 cubic.metres
hope its correct
