1.	The paint in a certain container is sufficient to paint an area of equal to 9.375 metre square. How many bricks of dimensions 22.5cm×10cm×7.5cm can be painted out of this container.
Answer» $\huge{ \mathtt{ \purple{SOLUTION:-}}}$ Number of the bricks that can be painted out of the container = Area that can be painted by the container/SURFACE area of brick Area that can be painted by the container =9.375m^2 $\large{ \implies{9.375 \times {100}^{2} {cm}^{2} }}$ $\large{ \implies{9.375 \times 10000 {cm}^{2} }}$ $\large{ \implies{93750 {cm}^{2} }}$ Total surface area of one brick = 2(lb+bh+hl) $\small{ \implies{2(22.5 \times 10 + 10 \times 7.5 + 22.5 \times 7.5) {cm}^{2} }}$ $\small \implies{2(22.5 + 75 + 168.75) {cm}^{2} }$ $\small \implies{(2 \times 468.75) {cm}^{2} }$ $\small \implies{ \bold{937.5 {cm}^{2} }}$ No. of bricks that can be painted out of the container = Area that can be painted by the container/surface area of the brick $\large{ \implies{ \frac{93750}{937.5}}}$ $\large{ \implies{ \frac{937500}{9375}}}$ $\large{ \implies{ \bold{100}}}$ Therefore, 100 bricks can be painted out by the PAINT.
