Question

three cubes,each measuring 6cm,are joined end to end.find the volume of resulting cuboid.

Answer 1

Hey mate..
========
Given,

3 cubes are joined together with each sides 6 cm.

We know,

Surface area of cuboid = 2(lb+bh+lh)

( where l= length of cube , b = breadth , h = height of cube )

Length of cube when 3 cubes are joined

l= l+l+l
= 6+6+6
=18 cm

surface area of cuboid = 2(lb+bh+lh)
= 2(18*6+6*6+18*6)
= 2(108+36+108)
= 504sqcm.
