Answer 1

Answer:

$\huge{\blue{\boxed{\green{\boxed{\red{\boxed{\bf{\mathcal{\purple{..S}\orange{O}\pink{L}\red{U}\blue{T}\green{ION..}}}}}}}}}}$

Volume of paint = 9.375 m² = 93750 cm²

Dimension of brick = 22.5 cm×10 cm×7.5 cm

Total surface area of a brick = 2(lb + bh + lh) cm²

= 2(22.5×10 + 10×7.5 + 22.5×7.5) cm²

= 2(225 + 75 + 168.75) cm²

= 2×468.75 cm2 = 937.5 cm²

Number of bricks can be painted = 93750/937.5 = 100

Hope this help you

Answer 2

Answer:

Given,

Area to be painted = 9.375 m2 = 9.375 x (100)2 = 93750 cm2

Dimension of brick = 22.5 cm×10 cm×7.5 cm

Number of bricks that can be painted out of the container = (Area painted by the container)/(Surface area of brick)

Total surface area of a brick = 2(lb + bh + lh) cm2

= 2(22.5×10 + 10×7.5 + 22.5×7.5) cm2

= 2(225 + 75 + 168.75) cm2

= 2×468.75 cm2

= 937.5 cm2

Therefore,

Number of bricks that can be painted = 93750 / 937.5 => 100

Hence, 100 bricks can be painted out of this container.
