Question

Three cubes each of volume 216m cube are joined end to end. The surface area of the resulting solid is

Answer 1

Answer:

Vol. of each cube = 216

Edge of each cube = 3√216

= 3√6×6×6

= 6 m

On joining 3 such cube end to end, it will form a cuboid .

Length = 6×3 = 18m

breadth = 6m

height = 6 m

SA = 2(lb + bh + lh)

= 2( 18×6 + 6×6 + 18×6 )

= 2 ( 108 + 36 + 108 )

= 2 × 252

= 504 sq. m Ans...
