7. Physical Science A small bar of gold measures 40 mm by 25 mm by 2 mm. One cubic millimeter of gold weighs about 0.0005 ounce, find the volume In cubic millimeters and the weight in ounces of this small bar of gold.
t. History A typical stone on the lowest level of the Great Pyramid in
Egypt was a rectangular prism 5 feet long by 5 feet high by 6 feet deep and weighed 15 tons. What was the volume of the average stone? Hoe much did one cubic foot of this stone weigh?
9. Hank has cards that are 8 inches by 4 inches. A stack of these aids fits inside the box shown and uses up 32 cubic inches of volume. How tall is the sock of cards? What percent of the box’s volume is taken up by the cards?

You’ll have to add most of the units because I didn’t

3. 12.5×24.25×x=3758.75, 303.125×x=3758.75 divide 303.125 from each side and get x=12.4

4. 4.5×x=18 divide 4.5 from each side and get x=4

5. 20×30×x=3600, 600×x=3600 divide 600 from both sides and get x=6

6. 3×3.5×1.5=V just multiply everything and get V=15.75 then multiply 15.7 by 7.5 and get 118.125

7. 40×25×2=V multiply everything and get V=2000 then multiply 2000 by. 0005 to get 1oz (not sure about the last part but I’m 99% sure it’s right)

8. 5×5×6=V multiply everything and get V=150 then multiply 150 by 15 to get 2250 (same with this last part)

9. 8×4×x=32, 32×x=32 divide each side by 32 and get x=1 and then 1% (Not sure about this one at all. But I tried. )
