Find the volume of the trapezoidal prism following.

60 cm³

Step-by-step explanation:

Applying,

Volume (V) = Area of the base(A)×Height(h)

V = Ah Equation 1

From the diagram,

A =  Area of Trapezium

A = 1/2(a+b)c Equation 2

Substitute equation 2 into equation 1

V = [1/2(a+b)c]h Equation 3

Given: a = 3 cm, b = 7 cm, c = 3 cm, h = 4 cm

Substitute these values into equation 3

V = [3(3+7)/2]4

V = (3×10/2)4

V = (3×5)4

V = 15×4

V = 60 cm³

the 4th choice is the correct one

step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.
