384 cubic centimeters.

Area = 1/2*(14+12)*8 = 104 square cm

Assuming that the prism is a right prism (with height perpendicular to the base plane), its volume is the product of the area of the base and the height. The area of the triangular base is one-half the product of the base and the height (altitude) of the triangle. Therefore, the volume in this instance is 4 X 3 X 12/2 = 72 cubic centimeters.

Area = 0.5*Base*Height So Base = 2*Area/Height = 2*114/12 = 19 metres.

The area of triangle is : 60.0

It is: 12 cm Check: 0.5*6*12 = 36 square cm

Area = 0.5*Base*Height So Base = 2*Area/Height = 2*114/12 = 19 metres.

Area = Base*Height so Base = Area/Height = 36/3 = 12 feet

The area of triangle is : 60.0

Area = Base*Height So 48 = Base*12 That is, Base = 48/12 = 4 m

Area = length * height. A = 20cm * 12cm A = 240 cm2

Area=18. Area= Base * height / 2 (12*3)/2
