the volume of a rectangular parallelepiped is 2,432 cubic units, and its edges are in the ration 2:3:5.what are the dimensions of the solid? find its total area.
-------------------
Equation:
(2x)(3x)(5x) = 2432
30x^3 = 2432
x^3 = 81.07
---
2x = 162.14
3x = 243.2
5x = 405.33
----
Total surface area:
A = 2[162.14*243.2+162.14*405.33+243.2*405.33]
