Question

The ratio of the length to the breadth to the height of a cuboid is 5 : 1 : 2
The total length of its breadth and height is 12 cm. Find its volume

Answer 1

Length = 5x , breadth = x , height = 2x Breadth + height = 12 => x+ 2x = 12 => x= 4 then length = 20 , breadth = 4 and height = 8 now volume = l X b x h = 20x 4x 8 = 640 cubic cm

Answer 2

the volume of the cuboid is 640V
