A1 = (1, -2 , 0) ; a2 = (0,1,2) ; a3 = (5,-6,8) ; b = (2,-1,6)
2*a1 = (2, -4,0)
3*a2 = (0, 3, 6)
-------------------
sum = (2, -1, 6) = b
Hope this helps
Answer:
512ft³
Step-by-step explanation:
A rectangular prism is made up of 32 cubes, each measuring 1 /4 of a foot per side. What is the volume of the rectangular prism?
Since we have 32 cubes with each side = 1/4 foot
= 32 × 1/4 foot
= 8
Hence, the volume of the rectangular prism = 8 × 8 × 8
= 512ft³
