Question

A block of wood of length 50 cm and area of cross-section 10em'. floats in water with of its length above water. Calculate density of wood in gcm-3? ​

Answer 1

Answer:

Since Volume of wooden block (V) = Cross Sectional Area (A) x Length (L), calculate volume (V) as follows : V = A x L = 10 x 50 = 500 cu. cm. Step-3 : Volume of wooden block immersed in water = (2/5) x 500 = 200 cubic cm
