You'd have to regroup twice.
Since 26 is bigger than 13, you'd need both the tens and ones places to go up by ten in order to subtract properly.
Ok so what you need to know about an octahedron is it's basically two square pyramids stacked on top of each other (one is upside down of course).
The formula for volume of a pyramid is Bh/3.
Base= 8*8=64
Height= 3 each
64*3/3= 64 mm^3 per pyramid.
64*2=128 mm^3 for the octahedron
Final answer: 128 mm^3
Answer:
2
Step-by-step explanation:
let the number be n, then
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
That is the number is 2
