about 71 cubic metres of gravel i think
To calculate the volume of gravel needed to fill a hole measuring 26 feet by 15 feet and 2 feet deep, you can use the formula for volume: length × width × depth. Thus, the volume is 26 ft × 15 ft × 2 ft = 780 cubic feet. Therefore, you would need 780 cubic feet of gravel to fill the hole.
That's not enough information. You need to know the width of the trench, and how much volume 1 ton of gravel is equivalent to.
You would need about 13 cu yards or about 15 tons.
Nor sure how pee gravel is packed, but you need enough for 64 cubic feet.
You will need 65.93 cubic yards or 84.6 tons of gravel.
