Question

a cuboid has length 1cm width 2cm height 8cm find a) volume b) surface area

Answer 1

a) Volume of cuboid= length*breadth*height
=1*2*8
=16cm³
b) surface area of cuboid=2(lb+bh+hl)
=2(1*2 + 2*8 + 8*1)
=2(2+16+8)
=2(26)
=52cm²

Answer 2

for volume l×b×h for surface area 2(l×b+b×h+h×l)
volume=1cm×2cm×8cm=16cm
surface area=2(1×2+2×8+8×1)
=2(2+16+8)
=2×26
=52cm
