The perimeter of the base of an equilateral triangular prism is 30 cm. The height of the prism is 17 cm. The volume of the prism is _______
425√3 cm3
Perimeter = 30 cm
Side of the triangle=perimeter3 =303=10 cm
Height h =17 cm
Area of base(A)=√34×s2
=√34×102
=√34×100
=√3×25
=25√3 cm2
Volume=A×h=25√3×17 =425√3 cm3
