3. An aquarium is in the form of a cuboid whose external measures are 70 cm x 28 cm x 35 cm. The base, side faces and back face are to be covered with coloured paper. Find the area of thepaperneeded. |
| Answer» GIVEN length = 70cm breadth = 28 cm height = 35 cm. Area of base = l * b = 70 * 28 = 1960 Area of side base = b * h = 28 * 35 = 980 Area of back face = l * h = 70 * 35 = 2450. Area of the PAPER needed = 1960 + 2450 + 2(980) = 1960 + 2450 + 1960 = 6370 cm^2. Hope this helps! | |
