It would be: 1500 - 1500*20/100 = 1500-300 = 1200
The volume would be V = (side of base)^2 * (height). The height would be 3. To see this, make yourself a model if need be. Assuming that the dimensions of the "square piece of cardboard" are x by x, then the length (or the width) of a side of the square bottom would be x-3-3, or x - 6.
So: V = (x-6)^2*3 = (area of base)*(depth of box)
= 3(x-6)^2 (answer)
Answer:
720 cm^3
Step-by-step explanation:
X=55, since straight lines are 180°. Y=70, since the triangle is isosceles, and the 2 bottom Angles are equal. Z=125, since the 2 opposite angles(x and y) add up to 125°
Answer:
30
Step-by-step explanation:
12.6 x
----- = -----
42 100
12.6 x 100 (1,260) / 42 = 30
