The volume of a triangular prism is the "area of a triangle" times the "thickness."
The area of a triangle is (base times height) over 2.
V = ((b*h)/2)*T
Given V = 2400 cu. cm, b = 16 cm, T = 20 cm, and h is unknown,
h = (2V)/(bL) = (2*2400)/(16*20) = 15 cm
Note that the given 17 cm in the picture is useless.
        
             
        
        
        
7 cm, it’s a step by step equation 
 
        
             
        
        
        
Every body has two hands so we have to multiply 66 by 2.
66 multiplied by 2 is equal to 132
The answer is 132.
