<u>Problem N 10) Find the surface area</u>
we know that
the surface area is equal to
SA=2*area of the base+perimeter of base*height
<u>Find the area of the base B (area of a square)</u>
<u>Find the perimeter of the base P (perimeter of a square)</u>
height=68 mm
substitute in the formula
therefore
<u>the answer Problem N 10) is</u>
the surface area is
<u>Problem N 11) Find the volume</u>
we know that
the volume is equal to
V=area of the base*height
<u>find the area of the base A (area of a triangle)</u>
height =4 ft
substitute in the formula
therefore
<u>the answer Problem N 11) is</u>
the volume is equal to
