Volume of a Hexagonal Prism

As we know,
Volume (V) = 3abh, here a = 8.7 m, b = 10 m, h = 12 m
∴V = 3 × 10 × 8.7 × 12
= 3132 cm³

Here we will use an alternate formula.
Volume (V) = ${\dfrac{3\sqrt{3}}{2}\times a^{2}\times h}$ , here b = 6.5 cm, h = 10.8 cm
∴V = ${\dfrac{3\sqrt{3}}{2}\times 6.5^{2}\times 10.8}$
≈ 1185.502 cm³

As we know,
The volume of an oblique hexagonal prism is same as the volume of a right hexagonal prism having the height ‘h’
∴Volume (V) = ${\dfrac{3\sqrt{3}}{2}\times a^{2}\times h}$ , here a = 9 cm, h = 15 cm
∴V = ${\dfrac{3\sqrt{3}}{2}\times 9^{2}\times 15}$
= 3156.67 cm³
