Volume of a smaller cube = (6)^3 cm^3 ( side = 6cm) => volume of 4 smaller cubes = 4 x (6)^3 cm^3 Now , volume of one larger cube (of side 8cm) = (8)^3 cm^3 => volume of three larger cubes = 3 x (8)^3 cm^3 => total volume of liquid = 4x(6)^3 + 3x(8)^3 => total volume = (4x3) (72 + 128) = 12 x 200 => total volume = 2400 cm^3 ....

Now , volume of one larger cube (of side 8cm) = (8)^3 cm^3
=> volume of three larger cubes = 3 x (8)^3 cm^3
=> total volume of liquid = 4x(6)^3 + 3x(8)^3
=> total volume = (4x3) (72 + 128) = 12 x 200
=> total volume = 2400 cm^3 ....
