A cylindrical tank is filled by pumping water from a cuboidal tank of dimensions 200cm × 150cm × 95 cm. The radius of the cylindrical tank is 60cm and height is 95cm. Find the height(in m) of the water left in the cuboidal tank after the cylindrical tank is completely filled. (Take π = 3.14)
A closed cuboid water tank is made of steel sheet that is 2.5 cm thick. The outer dimensions of the tank are 2.15 m, 1.5 m and 1.1 m. Find the total surface of the cuboidal tank.
