My Cube
MY CUBE!
If I covered my cube with gold paper I would need:
Left side 5x5=25
Right side 5x5=25
Top 5x5=25
Bottom 5x5=25
Other right side 5x5=25
Other left side 5x5=25
All together I would need 25+25+25+25+25+25=
The way I can work this out is: 20+20+20+20+20+20=120.
Then 5+5+5+5+5+5+=30.
After that I will add up the 2 totals that I got and that will be
my answer! 30+20=50+100=150 square cm!
Volume
Inside my cube there is enough room for 125 square cm lollies or blocks.
