Answer:

$120\ minutes$

Step-by-step explanation:

step 1

Alex’s printer

we know that

print 8 photos in 12 minutes

by proportion

Find how long will it take the printer to print 120 photos

$\frac{12}{8}=\frac{x}{120}\\ \\x=120*12/8\\ \\x=180\ minutes$

step 2

Khalil’s printer

we know that

print 24 photos in 1 hour (60 minutes)

by proportion

Find how long will it take the printer to print 120 photos

$\frac{60}{24}=\frac{x}{120}\\ \\x=120*60/24\\ \\x=300\ minutes$

step 3

Find the difference

$300\ minutes-180\ minutes=120\ minutes$

Answer:

Volume = ( About ) 2406.165 cm^3

Step-by-step explanation:

If you consider a cube or a rectangular prism, you could identify it's volume through the multiplication of it's Base by height. A pyramid has 1 / 3rd that volume, so in order to take a volume of the figure to the left, we would multiply Base * height and take 1 / 3rd of that;

$Square Pyramid,\\Base ( Square ) = a^2, a = length = 17.2 cm\\Height = 24.4 cm\\\\Volume = 1 / 3 ( Base ) ( Height ),\\Volume = 1 / 3 ( ( 17.2 )^2 )( 24.4 ),\\Volume = 1 / 3( 295.84 )( 24.4 ),\\\\Volume = 98.6133333333( 24.4 ),\\Volume = 2406.16533333,\\\\Volume = ( About ) 2406.165$
