Answer:
w = 2√155 ft ✅
Explanation:
Given that:
depth (d) = 10½ ft
Volume (v) = 6,510 ft³
Find the width (w) of the hole!
If the base is a square, then
the width and the length of the base is 'equal', so the
Volume of a cuboid =
V = w²d
width = square root of the division of volume by depth
w = √(V/d)
w = √(6,510/10½)
w = √620
w = √(4×155)
w = 2√155 ft ✅
