One cubic meter of water weighs approximately 2200 pounds. There are 100 cm in one meter. If you have a box-shaped fish tank tha

Diano4ka-milaya [45]

Answer:

158.4 pounds

Step-by-step explanation:

first find the volume of the tank

$V = 30 \times 30 \times 80$

$V = 72000 cm^3$

to convert this to m^3 we know that 1m = 100cm

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}}{100\,\text{cm}}\right)^3$

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}^3}{100^3\,\text{cm}^3}\right)$

the cm^3 cancel out.

$V = \dfrac{72000}{100^3} m^3$

$V = 0.072\,m^3$

by simply converting the side-lengths to meters beforehand can give you this answer directly:

$V = 0.3 \times 0.3 \times 0.8 = 0.072 m^3$

it is given that 1 meter cube of water weighs about 2200 pounds.

$1\,m^3 = 2200 \,\text{lb}$

multiply both sides with 0.072 to find our answer:

$1\,m^3 \times 0.072 = 2200 \times 0.072 \,\text{lb}$

$0.072\,m^3 = 158.4 \,\text{lb}$

hence the weight of the water in the tank would be 158.4 pounds!

help I will fail math class please help doors for the small cabinets are 11.5 inches long . doors for the large cabinet are 2.3

VARVARA [1.3K]

11.5 * 2.3 = large door size
large door size / 12 = large door size in feet
large door size in feet / 10 = how many large doors can be cut from the board. (you have to round it down if there's a decimal- no 1/2 doors.)

They're usually 365 days in each year every 4th year is call a leap year and has one extra day in February how many days are the

Mariana [72]

Answer:

Total number of days in 8 years is 2,922 days.

Step-by-step explanation:

Number of days in a Normal year = 365 days

Number of days in a leap year = 366 days

Also, Leap year comes exactly ONE TIME in every FOUR YEARS.

⇒ In every consecutive 4 years, 1 year is a leap year.

⇒ So, number of leap years in 8 years = 2

Now, 8 Years = 6 Normal years + 2 leap Years

<u>Number of days in 6 normal years</u>

= 6 x ( Number of days in a regular year)

= 6 x (365 days) = 2,190 days

<u>Number of days in 2 leap years</u>

= 2 x ( Number of days in a leap year)

= 2 x (366 days) = 732 days

So, Total number of days in 8 years

= Number of days in 6 regular years + Number of days in 2 leap years

= 2,190 days + 732 days

= 2,922 days

Hence, total number of days in 8 years is 2,922 days.
