Question

100 POINTS AND BRAINLIEST TO WHOEVER SOLVES IT

Answer 1

Answer:

See below ~

Step-by-step explanation:

Volume of a tetrahedon

• V = s³ / 6√2

1. s = edge length

Solving for V

• V = (4)³ / 6√2
• V = 64 / 6√2
• V = 32 / 3√2
• V = 32√2 / 6
• V = 16√2 / 3
• V = 7.54 cubic inches

Answer 2

Volume of a tetrahedron with edge s

$\\ \rm\Rrightarrow V=\dfrac{s^3}{6\sqrt{2}}$

According to question

• s=4in

$\\ \rm\Rrightarrow V=\dfrac{4^3}{6\sqrt{2}}$

$\\ \rm\Rrightarrow V=\dfrac{64}{6\sqrt{2}}$

$\\ \rm\Rrightarrow V=\dfrac{32}{3\sqrt{2}}$

$\\ \rm\Rrightarrow V=\dfrac{32}{4.2426406871192}$

$\\ \rm\Rrightarrow V\approx 7.5425in^3$
