One liter of paint is needed to cover all 6 sides of a cubical block. How many liters will be needed to cover all 6 sides of a s

Art [367]

Answer:

4 liters

Step-by-step explanation:

Let's assume that the side lengths of the cubical block are 2 inches.

This means that one of the sides area is 4 in².

Multiplying this by 6 (for there are 6 sides) gets us 24 in².

So one liter of paint covers 24 in².

Now if the side lengths (edge) of the second block is doubled, that means that the side lengths are $2\cdot2 = 4$ inches.

So the area of one side is 16 in².

Multiplying this by 6 (as there are 6 sides) gets us 96 in².

To find how many liters of paint this will take, we divide 96 by 24.

$96\div24=4$

So 4 liters of paint will be needed for the second cubical block.

Hope this helped!

A 13 ounce box of cereal cost $3.99. What is the unit price per pound?

goldenfox [79]

Answer:

I dont know how many pounds are in an ounce but I'll give you an explanation using kilograms and grams as an example and I'll talk you through it

Step-by-step explanation:

there are 1000 grams(g) in a kilograms (kg) just so you know

let's say I have a 13 g box of cereal for $3.99.

I do a ratio to work out 1 kg

13 g : $3.99

1000g : x

In your case your going to write

13 ounces : $3.99

[here write how many

ounces are in a pound] : x

to find x you 1st have to take the 2 numbers you do know and divide them

so in my example I do 1000g÷13 g = 76

then I take 76.92 and I multiply it by the other side

$3.99 x 76.92 = 306.91

for me 1kg of cereal is worth $306.91

all you need to do is replace my 1 kg with how many ounces are in a pound

mezya [45]

Answer:

Number of containers = 271

Total number of strawberries = 2172.

Number of strawberries per container = 8

Number of strawberry container = Total number of strawberries/Number of strawberries per container.

Number of strawberry container = 2172/8

Refer the figure to see division,

Number of containers = 271

Number of strawberries left = 4
