what is the question?
OpenStudy (anonymous):
oh im sorry
OpenStudy (anonymous):
What are the lateral area and the surface area of the box to the nearest whole number? Use the large 14 cm × 8 cm rectangles on the top and bottom as the bases.
OpenStudy (aripotta):
do you know the formulas?
OpenStudy (anonymous):
for lateral and surface? yea im pretty sure

tell me the formulas
OpenStudy (anonymous):
l=pi x r x slant height
s= l + b
OpenStudy (anonymous):
b= pi x r squared
OpenStudy (aripotta):
but this is a rectangular prism

hold up lemme find my notes sorry
OpenStudy (aripotta):
it's ok. you were probably using the wrong formulas the whole time
OpenStudy (anonymous):
l = (2l + 2w) h
b = l x w
s = l + 2b
OpenStudy (anonymous):
i didn't label these formulas so idk which is which
OpenStudy (aripotta):
so if the lateral area is h(2l + 2w), what's the lateral area?
