Class 9 Ganita Manjari Part 2 Math of Space Surface Area and Volume Question Answer
Since each cube has a volume of 125 cm³, the side length is the cube root of 125, which is 5 cm. Joining two cubes end-to-end forms a cuboid with length 10 cm, width 5 cm and height 5 cm. The total surface area is 2(lw + wh + hl) = 2(50 + 25 + 50) = 2 × 125 = 250 cm².
