40*60=2400
1/2 of 2400
=1200
Answer:
4.5^3 because we know v=lwh. since its a cube l, w, h will all equal 4.5
Answer:
height = 10.5 cm (for open-top container)
Step-by-step explanation:
The area of the base is ...
A = πr²
The lateral area is ...
A = 2πrh
We want the ratio of these to be 1:6, so we have ...
πr²/(2πrh) = 1/6
6πr² = 2πrh . . . cross multiply
h = 3r . . . . . . . divide by 2πr
h = 3(3.5 cm) = 10.5 cm
The height is 10.5 cm.
2/3 = 6/9 So,
6/9 + 2/9 = 8/9
3. 33 because x equals 6 so 5(6)+3 = 33
