@Phydeaux would u happen to know this , i have the form but dnt know y its not comming out right

anonymous · Answer

l=48

h=26

Sooo V= ((48^2)(26))/3

anonymous · Answer

Hmm. I get 19,968. Give me a sec.

anonymous · Answer

wut does pl mean again

anonymous · Answer

found my mistake.... I was using slant height rather than actual height. One sec.

anonymous · Answer

I got C. The height is 10,

so ((48^2)(10))/3=V

anonymous · Answer

thank u ya i was using 26

anonymous · Answer

You have to use pythagorean theorem to calculate the height rather than slant height, and use regular height. You're welcome. :]
