Question

Slant height =
Lateral area =
Altitude =
Total area =
Need to find these but need to know how not just formulas or a calculator site - thanks
Volume

Answer 1

slant height - use pythagors theorem on the triangle
5^2 = 3^2 + x^2
x = sqrt(25-9) = 4

lateral area = 1/2 * 6 * slant height = 3*4 = 12

altitude - use pythagoras on the red triangle
4^2 = 3)^2 + h^2
h = sqrt (4^2 - 3^2) = sqrt 7

Answer 2

total area = area of base + 4 * area of lateral sides
= 6^2 + 4* 12 = 84
