To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

1/9
2/3
Step-by-step explanation:
Disclaimer: Im in 4th grade and i know this so my advice is get bett-
a) Count the cubes, so 18
b) Volume is s^3 so (1/3)^3 is 1/9 for one cube
c) Volume for large solid is h*w*l so ({1/3)*3} times ({1/3)*3} times (1/3*2)
you get 1*1*2/3
so 2/3
