Find the volume of the candle using the formula for volume of a cylinder:

V = PI x r^2 x h = 3.14 x 3.4^2 x 6 = 217.79 cubic cm. Round to 217.8

Find the volume of the block: V = l x w x h = 15 x 12 x 18 = 3,240 cubic cm.

Now divide the volume of the block by the volume of a candle:

3240 / 217.8 = 14.88

Round to the nearest tenth = 14.9 candles.

lance bought a square postage stamp to a mail a card to his cousin. if the stamp has 4 square centimeters.what was the dimension
Lubov Fominskaja [6]

The dimension of one side of the stamp was 2 centimeters

Step-by-step explanation:

The formula of the area of any square is A = l², where l is the

length of the side of the square

lance bought a square postage stamp to a mail a card to his cousin

∵ The stamp has 4 square centimeters

∴ The area of the stamp = 4 cm²

∵ The stamp shaped a square

∵ The formula of the area of the square is A = l²

- Equate the formula of the area of the square by the area of the stamp

∴ l² = 4

- Take √ for both sides to find l

∴ l=\sqrt{4}

∴ l = 2 cm

The dimension of one side of the stamp was 2 centimeters

A contractor is hired to build an apartment complex. Each 840-square-foot unit has a bedroom, kitchen, and bathroom. The bedroom
Dennis_Churaev [7]

Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be x sq ft.

Then the area of kitchen will also be x sq ft.

Let the area of bathroom be y sq ft.

As per question statement:

x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

2x+2y=980 ..... (2)

Subtracting equation (1) from (2):

i.e. (2) - (1):

y = 140 sq ft

Putting the value of y in (1):

2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
