Answer:
The answer for your question is 2.
Step-by-step explanation:
The areas of the square pyramid are the amount of space on it
- The lateral surface area is 292.5 square cm
- The total surface area is 354.85 square cm
<h3>How to determine the lateral surface area?</h3>
The given parameters are:
Base (b) = 15 cm
Slant height (l) = 13 cm
The lateral surface area is calculated using:
L = 1.5bl
So, we have:
L = 1.5 * 15 * 13
Evaluate the product
L = 292.5
<h3>How to determine the total surface area?</h3>
This is calculated using:
T = L + 0.25√3b^2
So, we have:
T = 292.5 + 0.25√3 * 12^2
Evaluate
T = 354.85
Hence, the total surface area is 354.85 square cm

Volume is l * w * h
Length * width * height
to find the volume we would just plug in the values for the length width and the height.
4 * 16 * 20
64 *20 = 1280.
The volume of the box is 1280 cubic units.
The expression w = A/l can be used to find the width of the rectangle if the area and length of the rectangle are given.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let's suppose the width of the rectangle is w and the length of the rectangle is l
Then, the area of rectangle(A) can be given as:
A = lw
divide by l on both the sides:
A/l = lw/l
A/l = w
or
w = A/l
Thus, the expression w = A/l can be used to find the width of the rectangle if the area and length of the rectangle are given.
