Answer:
Total area of square base pyramid is 144 square units.
Step-by-step explanation:
It is given that pyramid has a square base with sides 8 and a slant height of 5.
[tex]a=8[/tex]
[tex]l=5[/tex]
Total area of square base pyramid is
[tex]A=a^2+2al[/tex]
Where, a is side length of square and l is slant height.
[tex]A=(8)^2+2\times 8 \times 5[/tex]
[tex]A=64+80[/tex]
[tex]A=144[/tex]
Therefore area of square base pyramid is 144 square units.
