What’s the surface area of the entire prism? You can use the calculator to help you solve. Remember, the surface area is the number of square units needed to cover all the faces without gaps or overlaps.

Question

Rectangular prism with length of 6 units, width of 2 units and height of 4 units.
Face Area
A 8 square units
B 12 square units
C 24 square units
D 24 square units
E 12 square units
F 8 square units
The surface area of the entire prism is
square units.

Answer 1

To find the surface area of the rectangular prism, you can sum up the areas of all the faces.

The areas of the faces given are:

• Face A: 8 square units
• Face B: 12 square units
• Face C: 24 square units
• Face D: 24 square units
• Face E: 12 square units
• Face F: 8 square units

Now, summing these areas together:

\[ \text{Total Surface Area} = A + B + C + D + E + F \] \[ = 8 + 12 + 24 + 24 + 12 + 8 \] \[ = 88 \text{ square units} \]

Thus, the surface area of the entire prism is 88 square units.
