a tea infuser is a right pyramid 7.9 cm tall. it's base is a rectangle 3.0 cm long and 15 cm wide. to make 1 cup of tea, the infuser must be 80% filled with tea. how many cups of tea can you make with a 100 ml tea container if you use this?

Full volume is:

80% of the volume of the infuser:

We know 100 ml = 100 cm³

Number of cups:

If you need a whole number then the answer is 9 cups

Note: The length of 3.0 cm doesn't make sense so changed it to 30 cm

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
