Hey there!
“6 + r = 8”
• FIRST: FIRST THE EQUATION
r + 6 = 8
• SECOND: SUBTRACT by 6 on BOTH SIDES
r + 6 – 6 = 8 – 6
CANCEL out; 6 – 6 because that gives you 0
KEEP: 8 – 6 because that helps solve for your r-value
• THIRD: SOLVE FOR YOUR EQUATION
8 – 6 = r
• FOURTH: ANSWER THE QUESTION
8 – 6 = 2
FIFTH: ANSWER
r = 2 ☑️
Good luck on your assignment and enjoy your day!

Number of 1/2-inch cubes length-wise = 8 1/2 ÷ 1/2 = 17
Number of 1/2-inch cubes width-wise = 5 1/2 ÷ 1/2 = 11
Number of 1/2-inch cubes height-wise = 2 1/2 ÷ 1/2 = 5
Number of 1/2-inch cubes = 17 x 11 x 5 = 935
