Answer:
Option A is the correct answer.
Explanation:
The given pyramid has 3 lateral triangular side as shown below.
Base of triangle = 12 unit
We need to find perpendicular.
By Pythagoras theorem we have
Perpendicular² = 10²-6²
Perpendicular = 8 unit
So area of 1 lateral triangle = 1/2 x Base x Perpendicular.
= 1/2 x 12 x 8 = 48 unit²
Area of lateral side = 3 x 48 = 144 unit²
Option A is the correct answer.

The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25
Let,
x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
Cost will be same when the functions are equal;
M(x) = U(x)
Dividing both sides by 0.10
The package weighs 30 ounces.
