12. Calculate the surface area of the rectangular prism.<br />
Draw and label the dimensions for each view.<br />
net of rectangular prism<br />
10 mm<br />
top or bottom front or back ends<br />
27 mm<br />
42 mm<br />
Find the area of each view:<br />
<strong>Area</strong> of top and bottom<br />
= 2 ×<br />
=<br />
<strong>Area</strong> of front and back<br />
= 2 ×<br />
=<br />
<strong>Area</strong> of 2 ends<br />
= 2 ×<br />
=<br />
<strong>Surface</strong> <strong>Area</strong> = (area of top and bottom) + (area of front and back) + (area of ends)<br />
= + +<br />

<strong>Area</strong> of triangle: <strong>Area</strong> of small rectangle: <strong>Area</strong> of large rectangle:<br />
S.A. = (2 × area of triangle) + (2 × area of small rectangle) + (area of large rectangle)<br />
= (2 × ) + (2 × ) +<br />
