Answer:
48 cubes can be cut from the wooden cuboid
Step-by-step explanation:
Total calculate this, we will first of all find the volume of the cuboid, and the volume of the cubes to be cut, then divide the volumes to see how many cubes can be cut from the cuboid.
Volume of cuboid = 12 × 12 × 9 = 1296 cm
volumes of each cube to be cut = 3 × 3 × 3 = 27 cm
Next, we will divide the volume of cuboid by the volume of the cubes:
Number of cubes = Volume of cuboid ÷ volume of cubes
Number of cubes = 1296 ÷ 27 = 48 cubes
Therefore, 48 cubes of sides 3cm can be cut from the wooden cuboid
i think that is is the second
This means that 2n is equal to or greater than -1 +10 or -1-10, which can be shown as 2n ≥ 9 and 2n ≥-11, and since 2n ≥11 encompasses both, we can therefore say 2n ≥-11 or n ≥ -5.5 by dividing both sides by 2
You want to find the closest ten thousand that there is to 639,121.
So a ten thousand is basically anything that ends with four or more zeros.
For example:
530000 would be a ten thousand because it has four zeros at the end.
So you can see what the closest ten thousands are to 639,121 would be.
They would be:
630,000 and 640,000
Since they both have four zeros at the end.
Now you can just tell that 639,121 is closer to 640,000 because the digit in the thousands place, 9, is closer to 10 than 0.
Hope this helped :)
