Answer 1

answer 23:

Solution:-

Thickness of brass plate = 1 mm or 0.1 cm

As the plate is in square shape, so the length and breath are same.

Length = x cm, breadth = x cm. and thickness = 0.1 cm

Volume = x² × 0.1 cm³

Given that 1 cu cm of brass has weight = 8.4 g

So, total weight = 8.4 × x² × 0.1

= 0.84x² gram

The weight of the plate = 4725 grams (Given)

⇒ 0.84x² = 4725

x² = 4725/0.84

x² = 5625

x = √5625

x = 75 cm

So the value of x is 75 cm.
