Surface Area and Volume

[Amanda[Miss Math]]

Ok guys, I know u are getting sooo tired of me! lol
But I need your help again! :?

Name of pyramid
Menkaure Pyramid in Egypt – a square pyramid

Base measurements
Side = 110 m

Height
70 m

I need to answer these questions based on the info. above, some of them (as you can see) I already answered...

Name of the Pyramid: Menkaure Pyramid
Find the Base Area (B). 110*110= 12100
Find the Slant Height (l). 89
Find the Lateral Area (LA).
Find the Surface Area (SA).
Find the Volume (V).

Find the Base Area (B). 110*110= 12100 m[sup:5g8v7607]2[/sup:5g8v7607]
Find the Slant Height (l). 89 m
Find the Lateral Area (LA). - Find the areas of the four slant triangles (bh/2 = 1/2 * 110 * 89 m[sup:5g8v7607]2[/sup:5g8v7607]). - add those up
Find the Surface Area (SA). - Add Base Area (B) to (LA)
Find the Volume (V). = ?/3 * (B) * (Height) m[sup:5g8v7607]3[/sup:5g8v7607]
