A cube whose volume is 1/8 cubic centimetre is placed on top of a cube whose volume is 1 cm3. The two cubes are then placed on top of a third cube whose volume is 8 cm3. The height of the stacked cubes is
Given,
Volume of 1st cube =
Volume of second cube = 1 cm3
Volume of third cube = 8 cm3
∴edge of first cube = a1 =
∴ edge of second cube = a2 =
∴ edge of third cube = a3 =
Hence height of cubes together = a1+a2+a3 =
