LA= ____√___
TA=____√___
V=(___√___)/___

figure will be written in my relpy

a regular pyramid

Answer 1

And the figure is...?

Answer 2

Right.

Answer 3

\[A_{lateral} = 3 \times A_{base}\]
\[ A_{total} = \sqrt3 \times l^2 \leftarrow\rightarrow 4 \times A_{base} \]
\[A_{base} = {\sqrt3 \over 4} \times l^2\]
\[V={1 \over 3} \times A_{base} \times H \leftarrow \rightarrow {\sqrt2 \over 12} \times l^3 \]
