Hello! Your answer was 19! There is no possible way for me to show you how to work this out using base ten blocks! Hopefully you can work it out in your head next time! :)
D=y2-y1
D+y1= y2-y1+y1 add y1 to both sides to cancel it out.
D+y1=y2 that drops -y1 for the right side but the left remains.
And that's your answer.
Find the area of one side, which is length x width:
2/3 x 2/3 = 4/9 square ft.
There are 6 sides to the prism, so multiply the area of one side by 6:
4/9 x 6 = 24/9 = 2 6/9 = 2 2/3 square ft.

1.2m
Step-by-step explanation:
1 meter = 100 cm
