A square brass plate of side x cm is 1 mm thick and weighs 4725 g. If one cc of brass weights 8.4 g, find the value of x.

KnowledgeBoat · Accepted Answer

Given, Side of square brass plate = cm Here, l = cm and b = cm Thickness of plate = 1 mm = = 0.1 cm We know that, Volume of the plate = l × b × h Substituting the values = × × 0.1 = cm³ Given, Weight of 1 cm³ of brass = 8.4 g ∴ Weight of cm³ of brass = 8.4 x g But weight of square brass plate is given as 4725 g Hence, x = 75.
