Answer: I am very late but the answer is A if you were still wondering
Step-by-step explanation:
<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
Sylvia is correct. This is because the sum of angles in a triangle is 180° and a triangle has 3 angles. If it had 2 right angles (90° each) it would already equal 180° and that's not possible because a thrid angle has to exist.
Hope I helped!
Well, is very plain vanilla.
notice, the square pyramid has a square on its base, thus is called that, the base is 4x4 in area.
it also has 4 triangular faces, each triangle has a base of 4 and an altitude or height of 6.
sum up the area of the base and the triangular faces, and that's the total area of the pyramid.
