Estimate the depth of the lake

Reference no: EM13490383

A 1.5-m-long glass tube, closed at one end,is weighed and lowered to the bottom of a fresh-water lake. When the tube is recovered, an indicator mark shows that water rose within 0.40 m of the closed end. Determine the depth of the lake. Assume constant temperature.
