Question

the paint in a certain container is sufficient to paint an area equal to 10.865m^2. How many bricks of dimensions 31.5cm × 10cm× 5.5 cm can be painted from that paint?​

Answer 1

Step-by-step explanation:

to find how many bricks you already know that if we want to paint a house we not only paint four wals right so we have to paint top and botyom also for that wehave to use tsa of cubiod

Answer 2

Answer:

100 bricks can be painted from that paint.

Step-by-step explanation:

Dimensions of each brick are given as 31.5 cm × 10cm × 5.5cm.

If we convert these dimensions in meters then the given dimensions will be 0.315m × 0.10m × 0.055m

Since surfaces of each brick are to be painted so surface area of each brick will be = 2(length×width + width×height + length×height)

= 2(0.315×0.10 + 0.10×0.055 + 0.315×0.055)

= 2(0.0315 + 0.0055 + 0.017325)

= 2(0.054325)

= 0.10865 m²

Now we know a paint container is sufficient to paint the area = 10.865 m²

Therefore, number of bricks required = $\frac{\text{Total surface area painted}}{\text{Surface area of one brick}}$

                                                              = $\frac{10.865}{0.10865}$

                                                              = 100 bricks
