Question

Three cubes of volume 27cm cube each are joined end to end to form a solid. Find the surface area of the cuboid so formed.

Answer 1

ANSWER:-✅✅⤵️⤵️

volume of cube=27cm^3

(edge)^3=27cm^3

edge=3cm

Now dimensions of Cuboid are 3,3 and 6

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

=2(3×3+3×6+6×3)

=2(9+18+9)

=2(36)=72cm^2

Answer 2

Answer:

Step-by-step explanation:

Volume of cube = a cube

So volume is given to us

Therefore

27 = a cube

a = 3

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

= 2 ( 3×6 +3×3 + 3×6)

= 2 ( 18 + 9 +18 )

= 2 (45)

= 90
