Question

2 cube each of 10 cm edge joined end to end find the surface area of the resulting​

Answer 1

Answer:

Step-by-step explanation:

If we join two cubes.Then, for new cubes

length = 10+10 =20cm

Beadth = 10cm

height = 10cm

Here , only length will be changed which will change cube into cuboid.

Now ,

Surface area of resulting cuboid

= 2(lb+bh+hl)

=2(20×10+10×10+10×20)

=2(200+100+200)

=2×(500)

=1000 cm square...
