Question

Cubes each of volume 64cm^3are joined end to end.find surface area of resulting cuboid.
Please solve this question.......

Answer 1

hey mate✌✌✌

here is your answer✍✍✍

64 cm^3 =volume

4 cm = side

length of resulting cuboid =3×4 =12 cm

bredth =4 cm

height =4 cm

TSA of cuboid

=2(12*4+4*4+12*4)
=2(48+16+48)
=2(112)
=224

hope it helps u....☺☺

Answer 2

1st the side of cube whose volume is 64cm^3

a^3=64^3

a=4 cm

If we will join three cube of side 4cm than the length of resulted cuboid is 12 cm and height and breath will remain 4 cm

surface area of vubiod = 2(lb+bh+hl)

=2(12×4+4×4+4×12)

=2(48+16+48)

=2(112)

=224 cm^2
