Answer:
Step-by-step explanation:
Given:
rectangular prism
volume of 360 cubic units
height is 10 units
Volume = length * width * height
360 cubic units = lw * 10 units
360 / 10 = lw
36 = lw
The only measure of the sides of a square base is 6 units. 6 is the square root of 36.
To prove that the base of the prism is not a square, its measure should be
length = 9 ; 18 ; 12
width = 4 ; 2 ; 3
V = 9 x 4 x 10 = 360
V = 18 x 2 x 10 = 360
V = 12 x 3 x 10 = 360
Answer:
Side a = 23 Side b = 28 Side c =46
Step-by-step explanation:
First set up your equation witch is x-5+x+x-5*2=69
Then Simplify x+-5+x+x+-10=69
Then combine like terms 3x-15=69
Add 15 to both sides
After you will get 3x=84
then divide both sides by 3
You will get x=28
Then go back to your question it says THE FIRST IS 5 CM SHORTER THAN THE SECOND SIDE. THE THIRD SIDE IS TWICE AS LONG AS THE FIRST SIDE. So that tells you that to find A, you do 28-5=23, to side b is x so its 28, and to find side c you do 28-5*2=46. So A=23, B=28, and C=46.
Answer:
Simply divide 12 by 111.
12/111 = 0.10810811 (you can round it to 0.11 though)
Hope this helps! :)
