1 |
Problem |
A rectangular prism of volume \$4200(mm)^3\$ has a rectangular base of length 5 mm and width 8 mm. Find the height h of the prism. |
|
2 |
Step |
Given that the volume(v) of the rectangular prism is length(l) is width(w) is |
\$4200(mm)^3\$ 5 mm 8 mm |
3 |
Formula: |
Volume of rectangular prism is |
\$"Volume"(v) = "length" times "width" times "height"\$ |
4 |
Step |
Substitute the values into the formula |
\$4200(mm)^3 = 5 mm times 8 mm times h\$ |
5 |
Step |
solve for the height (h) |
\$"h" = (4200(mm)^3) / (5 mm) times 8 mm\$ \$"h" = (4200(mm)^3)/(80(mm)^2)\$ \$"h" = 4200/80 = 105 mm\$ |
6 |
Step |
So, the height (h) of the rectangular prism is 105 mm. |
