Explanation:
Let b is breadth and l is length of the cuboid such that,
Length, l = 3b and l = 2h
or
h = l/2
We know that, the volume of a cuboid box is given by :
V = lbh
Put all the values,
![V=l* (l)/(3)* (l)/(2)\\\\750=l* (l)/(3)* (l)/(2)\\\\750* 6=l^3\\\\l=(750* 6)^(1/3)\\\\l=16.5\ cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/j0t660wl9z2z9qktrfj2rr2ch9ulq8b0cy.png)
Breadth, b = 16.5/3 = 5.5 cm
Height, h = 16.5/2 = 8.25 cm
Hence, this is the required solution.
