Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : 
Where l is length, w is width, and h is height
Plugging in the new values we get:

The surface area of the enlarged prism = 376 cm^2
PEMDAS.....parenthesis, exponents, multiplication/division, addition/subtraction
so step 2 is solving the exponents <==
Consider the number 1457.506
We have to round it to the nearest hundredth.
Consider the digit at hundredth place which is '0'. Now, consider the digit next to the hundredth place. Since, the digit next to the hundredth place is '6' and it greater than 5. Therefore, we will add '1' to the hundredth place.
So, the number rounded to the nearest hundredth is 1457.51
Dear Gabyobag, what you do is do 13 ÷ 1/6 -> 13 x 6 ->78 floors.
Answer:
-1/2
Step-by-step explanation:
Point L is at (-2,3)
Point M is at (2,1)
We can find the slope using
m =(y2-y1)/(x2-x1)
= (1-3)/(2 - -2)
=(1-3)/(2+2)
=-2/4
=-1/2
