The volume of a pyramid is the product of its base area and height, divided by 3.
The true options are (a) XY and ST
, (b) VU and TW and (d) TX and WX
The volume of the hexagonal right pyramid is:
[tex]\mathbf{V = \frac 13 a^2h}[/tex]
Where: h represents the height, and (a) represents the side lengths.
So, by comparison:
[tex]\mathbf{a = XY =YZ = ZU = UV = VW = WX}[/tex]
[tex]\mathbf{h = ST}[/tex]
So, lengths XY and ST can be used to determine the volume of the pyramid.
Other lengths that can be used are: VU and YZ, and TX and WX.
This is so because:
Lengths VU and WX can be used to calculate the area (a^2), while lengths YZ and TX can be used to calculate height (h)
Hence, the true options are (a), (b) and (d)
