Answer:
310 cm3
Step-by-step explanation:
4 area of triangle = 60
Area of cuboid = 250
Total volume = 310cm3
A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer
She Bought 23 shirts because if you do 400-50 you get 350 the / by 15 wich give you 23.333333ect
