Question 11
The dimensions of two metal cuboids are $3\times5\times7$ and $6\times8\times10$. One of the cuboids is shown on the right. Harry melts both cubes and forms the largest possible cuboid with base of size $9\times13$. What is the height of the new cuboid?
Interpretation: “Both cubes” in the original means the two cuboids. Assume no metal is lost and all dimensions use the same length unit.
