Answer:
formula : 1/3 πr3
so this can be done this way
v=1212
22/7 X 1/3 X r3 =1212
r3=1212 X 7 X 3/22
r3=1156.909091
r=10.48
so surface area=
πrl
l=(10.48 X 10.48)+(24 X 24)
=√109.8304 + √576
= 26.1883638
ar=22/7 X 10.48 X 26.1883638
=862.5698797 cm3
Step-by-step explanation:
r3= radius cube
cm3= centimeter cube
