### Rectangular Prisms – Example 1:

Find the volume and surface area of the following rectangular prism.

**Solution:**

Find the volume and surface area of the rectangular prism.

Use volume formula: **Volume** \(=l×w×h\) , \((l=6 , w=4 , h=8)\)

Then: **Volume** \(=6×4×8=192\) \(m^3\)

Use surface area formula: **Surface area** \(=2(wh+lw+lh)\)

Then:** Surface area** \(=2((4×8)+(6×4)+(6×8))\)

\(=2(32+24+48)=2(104)=208\) \(m^2\)

### Rectangular Prisms – Example 2:

Find the volume and surface area of the following rectangular prism.

**Solution:**

Find the volume and surface area of the rectangular prism.

Use volume formula: **Volume** \(=l×w×h\) , \((l=10, w=5, h=8)\)

Then: **Volume** \(=10×5×8=400\) \(m^3\)

Use surface area formula: **Surface area** \(=2(wh+lw+lh)\)

Then:** Surface area** \(=2((5×8)+(10×5)+(10×8))\)

\(=2(40+50+80)=2(170)=340\) \(m^2\)
