Question

Two cubes of volume 64cm^3 are joined end to end. Find the volume of the sphere.
​

Answer 1

Step-by-step explanation:

volume of cube=a^3

a=3√64

a=4cm

Since two cubes are joined end to end the new solid is a cuboid

volume of a cuboid=l*b*h

l=4+4=8cm

b=4cm

h=4cm

volume=8*4*4

=128cm^3

Answer 2

Answer:

volume of a cube = a^3=64cm^3

a=cubth root 64

a=4cm

since cubes are joined end to end the new solid is a cuboid

volume of a cube=lbh=l=4+4=8cm

b=4cm

h=4cm

volume of new figure =8×4×4=184cm^3
