75.
There are 75 girls in the classroom.
We're looking for the total so we need to add 65 with 75.
65+75= 140.
There are 140 total students.
The cone has the smallest volume of the 2 figures. This is because formula for cylinder is <em>b x h</em>, the formula for cone is <em>1/3(b x h)</em> so if they have <em />same height and <em>base area</em> cylinder would have larger volume because for cylinder, formula is one-third of <em>b x h. </em>Hope I helped!! : )
Pick b because 4 is a sum and you tryna find the number that go with z

Find volume of pyramid
Formula for volume of pyramid
= (height * length * width) ÷ 3
Height = 4mm
B (base = area = length x width) =15mm^2
Volume = (4mm * 15mm^2) ÷ 3
= 60 ÷ 3
= 20 mm^3
