Question

A cuboid has a volume of 135cm^3 the area of the base of the cuboid is 15cm^2. work out the height of the cuboid​

Answer 1

volume of cuboid =l×b×h=448cm

3

=l×b×7=448cm

3

=l×b=64cm

2

but base is square

∴l=b

∴l

2

=64cm

2

⇒l=b=8cm

surface area =2(lb+lh+bh)

=2(8×8+8×7+8×7)

=2(64+56+56)

=352cm

Answer 2

Answer:

Base area=l×b=15cm^2

Volume of cuboid=l×b×h=135cm^3

Height=l×b×h/l×b

=135/15

=9cm
