I need help i been trying it a lot on num 7

B

Step-by-step explanation:

Okay, for this question they give you the height and the volume.

The formula is: W×L×H

So since you know W×L×8=250

You would just find two other numbers that give you 250 with 8.

A.)5×6×8= 240

B.)5×6.25×8=250

C.)5.25×6×8=252

D.)5.5×6.25×8=272

So the correct answer is B

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
