Trent has an 6-foot tall tent in the shape of a square base pyramid with a base length of 14 feet and slant height of 8 feet. If one bottle of waterproof spray covers 75 square feet, how many bottles will he need to waterproof his tent?

Trent needs _______ bottles

Respuesta :

Answer:

6 bottles

Step-by-step explanation:

14*8=112   112/2=56    56*4=224ft^3 (surface of all triangles)

14*14=196ft^3 (surface of square base)

224+196=420ft^3

420/75=5.6

Trent needs 5.6 bottles, and if you round 6 bottles.
