Question
Four cubes, each with a side length of 8 cm, are connected
in a straight line to form a cuboid. Calculate the total surface area of the resulting cuboid.Solution
Length of cuboid = 4 X 8 = 32 cm
Breadth of cuboid = 8 cm
Height of cuboid = 8 cm
Total surface area of cuboid = 2 X (lb + bh + hl) , where 'l', 'b' and 'h' are length, breadth and height respectively
So, required area = 2 X (32 X 8 + 8 X 8 + 8 X 32) = 2 X (256 + 64 + 256) = 1,152 cm 2
