Given a container that is 4.50 ft. by 7.20 ft. that is filled with water 5.00 inches deep.What is the volume of water in liters

elena55 [62]

Answer:

382.3 liters

Step-by-step explanation:

We are told in the question that:

A container that is 4.50 ft. by 7.20 ft. that is filled with water 5.00 inches deep.

This means:

Length = 4.50 ft

Width = 7.20 ft

Depth(Height) = 5.00 inches

We have to convert all of these to centimeters first. Then to liters

1 foot = 30.48 centimetres

1 inch = 2.54 centimetres

Length = 4.50 ft

1 foot = 30.48 centimetres

4.5 ft = 4.5 × 30.48

= 137.16 cm

Width = 7.20 ft

1 foot = 30.48 centimetres

7.20 ft = 7.20 × 30.48 cm

= 219.456cm

Depth(Height) = 5.00 inches

1 inch = 2.54 centimetres

5 inches = x cm

Cross Multiply

= 5 × 2.54 cm

= 12.7 cm

The volume of the water(cm³) = Length × Width × Depth

= (137.16 × 219.456 × 12.7)cm³

382277.428992 cm³

The volume of water in liters

1 cubic centimetre = 0.001 litre

382277.428992 cm³ = x

Cross Multiply

382277.428992 cm³ × 0.001 litre

= 382.2774289920001 liters

Approximately = 382.3 liters

A sailboat's Saul has three sides that are all the same length. Each side measures x - 10 units. The sail's perimeter is 63 unit

ruslelena [56]

Answer:

The value of 'x' is 31 unit

Step-by-step explanation:

Given:

Measure of each side = $x-10\ units$

Perimeter of sails = 63 units.

We need to find the value of x.

Solution:

Now we can see that from given data.

A sailboat's Saul has three sides.

Now assuming it to be triangle we get;

"Perimeter of triangle is equal to sum of all side."

So we can say that;

$x-10+x-10+x-10 =63\\\\3x-30=63$

Now adding both side by 30 we get;

$3x-30+30=63+30\\\\3x=93$

Now dividing both side by 3 we get;

$\frac{3x}{3}=\frac{93}{3}\\\\x=31 \ units$

Hence the value of 'x' is 31 units.
