If John has $0.75 and he needs $2.50, then you will subtract $0.75 from $2.50 to find out how much he needs which is $1.75. Hope I helped! Don't forget to help me with the Brainliest Answer! :D
1e+6 is the amount of cubic CM (or one million 1000000)
X=6 and Y= 6 square root 2
You weren't clear on instructions
So first calculate root of 3 which is 1.732
Next multiply by 8 to get 13.856
Hope this helps:)
