An aquarium has a base in the shape of a trapezoid. The base is 100

Nat2105 [25]

Answer:

$Volume = 210L$

Step-by-step explanation:

Given

Base:

$Front = 100cm$

$Back = 50cm$

$Width = 40cm$

$Height = 70cm$

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

$Area = \frac{1}{2}(Front + Back) * Width$

$Area = \frac{1}{2}(100cm + 50cm) * 40cm$

$Area = \frac{1}{2}(150cm) * 40cm$

$Area = 75cm * 40cm$

$Area = 3000cm^2$

$Volume = Area * Height$

$Volume = 3000cm^2 * 70cm$

$Volume = 210000cm^3$

$1cm^3 = 0.001L$

So:

$Volume = 210000 * 0.001L$

$Volume = 210L$

It takes 63 minutes for 4 people to paint 9 walls.

alukav5142 [94]

Answer: 7 people need 16 minutes to paint 4 walls.

Step-by-step explanation:

Since we have given that it takes 63 minutes to paint 9 walls ,

So, we will apply "time and work formula" i.e.

$\frac{M_1\times D_1\times H_1}{W_1}=\frac{M_2\times D_2\times H_2}{W_2}$

where,

H denotes number of hours or minutes,

D denotes number of days

M denotes number of men

W denotes work done them,

So, we need to calculate number of minutes for 7 people to paint 4 walls,

$\frac{63\times 4}{9}=\frac{M\times 7}{4}\\\\7\times 4=\frac{M\times 7}{4}\\\\16=M$

So, 7 people need 16 minutes to paint 4 walls.
