The right triangular prism has a volume of 1,152 cm3. what is the value of x, the height of the prism? 6 8 12 16

volume = 1/2 x a x b x X

1152= 1/2 x 12x 12 x X

 12*12 = 144

1152 = 1/2 x 144 x X

1152/ 1/2 = 2304

2304 =144 x X

X=2304/144 = 16

check  1/2*12*12*16 = 1152

x=16cm

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
