What is the volume of this triangular Pyramid photo attached
storchak [24]

To find the volume of a triangular pyramid, the formula is:

V=\frac{1}{3}(Area\text{ }of\text{ }thebase)(height)

So we start by finding the area of the base, which is in the shape of a right triangle in this case.

The area of a right triangle is equal to 1/2 x base x height.

\begin{gathered} A=\frac{1}{2}bh \\  \\ A=\frac{1}{2}(5)(6) \\  \\ A=15\text{ square feet} \end{gathered}

We use this area to find the volume.

\begin{gathered} V=\frac{1}{3}Ah \\  \\ V=\frac{1}{3}(15)(6) \\  \\ V=30\text{ cubic feet} \end{gathered}

The volume of the triangular pyramid is 30 cubic feet.

The area of trapezium is 1586cm² and the distance between sides is 26cm.If one of the parallel sides is 84cm,find the other​
irinina [24]

Check the picture below.

we know the area is 1586, so

\stackrel{\textit{area of a trapezoid}}{A=\cfrac{h(a+b)}{2}}\implies 1586=\cfrac{26(84+b)}{2}\implies 1586=13(84+b) \\\\\\ \cfrac{1586}{13}=84+b\implies 122=84+b\implies 38=b
