Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches
area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches
Answer:
j= -38
Step-by-step explanation:
1÷2j+7=-12
j+14=-24
j=-24-14
j=-38
Answer:
y=8x-4
Step-by-step explanation:
y=mx+b
m=8
b (y intercept)= -4
y=8x-4
Take 82 1/2 ÷ 2 1/2 = - 36 1/3 ft per min
