What is the total surface area of the square pyramid 8in 5in

A≈166.45 in^2

Step-by-step explanation:

A=a^2+2a√(a2/4+h^2)

a = base = 8 in

h = height = 5 in

A = 8^2+16√(8^2/4+5^2) = 166.449... in^2

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading

step-by-step explanation:

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
