Question

A MARBLE TILE MEASURE 25 CM BY 20 CM . HOW MANY TILES WILL BE REQUIRED TO COVER A WALL OF SIZE 4cm
BY 3cm​

Answer 1

Correct Answer --

• 240 Tiles

${\pmb{\underline{\sf{Required \: Solution....}}}}$

Given :-

• Dimensions of the Marble = 20 cm × 25 cm
• Dimension of the Wall = 4m × 3 cm

To find :-

• Number of Required Tiles

Solution :-

➠ Rectangle (Marble tile Area)

= 25 cm × 20 cm

= 500 Cm ²

➠ Cover of wall's Area

= 4m × 3m

= 12 m²

● Convert into CM (Cover of wall's Area)

We know that ;

$\: \: \: \: \boxed {1m = 100cm} \\ : \implies12 \times 10 {}^{4} \: m {}^{2}$

Number of Required Tiles = $\boxed { \frac{area \: of \: the \: wall \: cover}{marble \: tile \: area} }$

$\implies \frac{12 \times 10 {}^{4} }{500} \\ \\ \implies \frac{1200}{5} \\ \\ \implies \boxed{240}$

Number of required tiles is 240 .
