To find volume you use the formula length×widght×height
12 × 7 × 17
Which equals 1428
X-intercept: y = 0
y-intercept: x = 0
3x + 4y = 0
x-intercept: subtitute y = 0
3x + 4 · 0 = 0
3x = 0
x = 0 → (0; 0)
y-intercept: subtitute x = 0
3 · 0 + 4y = 0
4y = 0
y = 0 → (0; 0)
84/56 =69/x
84x = 69 x 56
x = (69 x 56)/84
x = 46
