Find the surface area of the resulting cuboid. Solution: Volume of one cube = X 3 Side of one cube = (X 3 ) 1/3 If we join two cubes, then it will form a cuboid. Then the length of the cuboid = 4 cm + 4cm = 8cm. Height of the cuboid = 4cm Width = 4cm Therefore, the total surface area of the cuboid = 2(lb + b*h + h*l) ...
