Question

Three cubes of volume 64 cm3

each are joined face to face to form a solid cuboid. Find

the surface area of the cuboid so formed.​

Answer 1

Answer:

hope it will help you out

Step-by-step explanation:

Volume of each cube = 64 cm3

Thus, side of each cube 4 cm

So, the dimensions of cuboid are 4 x 4 x 12.

. Surface area of the cuboid = 2[4 x 4 + 4 x 12 +12 x 4]

= 224 sq. cm

Answer 2

Answer:

Volume of cube=S*S*S

64=S^3

S=side=4 cm

therefore

breadth of Cuboid= 4cm

Length of cuboid=4+4+4

=12cm

Height of the cuboid=4cm

therefore surface area=2(LB+BH+LH)

=2[(12*4)+(4*4)+(12*4)]

=2(48+16+48)

=2*112

=224cm^2
