What’s the answer to this
LenaWriter [7]

Hello!


We need to find the height of the kite in order to find the volume. We are given the surface area, which is the area of each face added up. As you can see, we can see, based on our given information, we have 1800 with the top and bottom. We can write an equation to solve below.


1800+60h+60h=7200

1800+120h=7200


Now we solve. First we subtract 1800 from both sides.


120h=5400


Divide both sides by 120.


h=45


Just to make sure, we will plug our height into the equation to make sure it is true.


1800+2700+2700=7200


Now we just multiply our base by height.


900(45)=40,500


Therefore, the volume is 40,500 cm³.


I hope this helps!

How do i convert 4.5 meters into cm
REY [17]

Answer: 4.5 meters is 45 centimeters.


Step-by-step explanation: The centimeter is just a single digit behind a meter, or in more mathematical terms, a tenth of a meter.

In this case, you can simply multiply 4.5 by 10 or divide 4.5 by one hundreth (or 1/100). In doing so, you'd successfully acheive the value of 45. Study your conversions

How much should you invest at 3.7% simple interest in order to earn $70 interest in 11 months?
valkas [14]

Step-by-step explanation:

in this condition we are given simple interest time and rate

so principal is missing so we should use the formula of principal that is

P=I×100/T×R

but we should convert that month in to years and we convert it by dividing it by 12.
