Question

2 cubes each of volume 64 cm 3 are joined end to end find the volume of the sphere

Answer 1

Answer:

given volume of cubes=64

then side=4

length of resultant cuboid=8

height=4,bredth=4

volume=4*8*4=128

Answer 2

$\huge\bold\star{\fcolorbox{blue}{pink}{Solution}}$

$\leadsto$ Volume of Cube = ${s}^{3}$

${s}^{3} = 64 \\ s = \sqrt[3]{64} \\ s = 4$

Length(l) = 8cm

Breadth(b) = 4cm

Height(h) = 4cm

$\leadsto$ Surface Area of Cuboid = 2 (lb+bh+hl)

= 2 (8*4 + 4*4 + 4*4)

= 2 (32 + 16 + 32)

= 2*80

= 160 ${cm}^{2}$
