Question

a cuboid has l=12cm and b=9cm find height and volume when total surface area=426cm square

Answer 1

Answer:

I have forgotten the formula if you have learnt then solve it with your own

Answer 2

TSA of cuboid=426,volume=540

l=12,b=9,h=5.

TSA of cuboid=2(lb+bh+lh)

=2(12×9+9×5+12×5)

=2(213)

=426cm2

volume of cuboid=lbh

=12×9×5

=540cm3
