Homework Statement
Determine the volume of foam needed to support one cargo block with the following conditions. The bottom of the block is 2 cm above the water line and when viewed from the top there is 1 cm of foam around all edges of the cargo block.
The dimension of the block are 3.5 cm high x 3.5 cm x 7.5 cm. It weighs 70 g.
The Attempt at a Solution
I realize this is probably a very simple problem but I just can't manage to wrap my head around it. I know that in order for the block to float the buoyant force exerted by the water must be equal to the weight of water displaced by the block but other than that I'm completely stumped any help would be great.
