Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
Answer: 3 units right 6 units up
Step-by-step explanation:
coordinate B was first (3,3)
then became (6,9)
X axis is 3 which is left and right
Y axis is also 3 which is up and down
right = positive left= negative up=positive down=negative
the math
you have to add 3 to the right to get positive 6
so the coordinates so far are (6,?)
then you need to add 6 on the y axis for the coordinates to be (6,9)
hope this helped
U say the answer is D 7$......
I guess 52inches as volume of a prism=Base area x Height
