One can be L = 20 cm; W = 20 cm; H = 6 cm
The other can be: L 16 cm; W = 15 cm; H = 10 cm
Easy, 1/4 because there are 1/2 and you'll slice the 1/2 half which is equal to 1/4
we know that
Each pizza has a diameter of 20 cm-------> is equal to 200 mm
<u>Divide 640 mm by 200 mm</u>
640/200=3.2---------> 3 pizzas
<u>Divide420 mm by 200 mm</u>
420/200=2.1-------> 2 pizzas
therefore
The number of pizzas that can Riona fit on one baking tray is
3*2=6 pizzas
<u>the answer is</u>
6 pizzas
I would love to help but there is no pic
