Find the volume to the triangular pyramid.

Known :

pedestal = square

side of square = 14 m

height of triangle = 18,2 m

Asked :

Volume = ...?

Answer :

Find the height of pyramid first (Phytagoras Theorem) :

h² = h of triangle² - ½ s of square²

h² = 18,2² - (½×14)²

h² = 331,24 - 7²

h² = 331,24 - 49

h² = 282,24

h = √282,24

h = 16,8 m

Now, lets find the volume :

V = ⅓ × pedestal area × height of pyramid

= ⅓ × (14 × 14) × 16,8

= ⅓ × 196 × 16,8

= ⅓ × 3.292,8

= 1.097,6 m³

So, the volume is 1.097,6 m³

Hope it helpful and useful :)

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
