A strip of sheet metal 30 cm wide is to be made into a trough by turning strips up vertically along 2 sides.
How many cm should be turned up at each side to obtain the greatest carrying capacity?

Help pls
Thanks in advance
max capacity will occur when the cross-sectional area (a rectangle) is a maximum.
let x = length of metal to be turned up on both sides
