The surfaces of the bottom is 45 * 45 = 2025 cm2.
Then the height of the box is 151 875 / 2025 = 75 cm
Answer:
b=r-9/9
Step-by-step explanation:
First you do the distributive property...
r=9b+9
then you subtract the 9
r-9=9b
then you divide the 9
r-9/9=b
and because of the symetry property you can flip it...
b=r-9/9
