On the left, prism A. Prism A is a triangular prism. The base has side lengths of 6 centimeters, 8 centimeters, and 10 centimete
Llana [10]

Answer:

Prism B has a larger base area

Step-by-step explanation:

Given

Base dimensions:

Prism A:

Lengths: 6cm, 8cm and 10cm

Prism B:

Lengths: 5cm and 5cm

Required [Missing from the question]

Which prism has a larger base area

<u>For prism A</u>

First, we check if the base dimension form a right-angled triangle using Pythagoras theorem.

The longest side is the hypotenuse; So:

10^2 = 8^2 + 6^2

100 = 64 + 36

100 = 100

The above shows that the base dimension forms a right-angled triangle.

The base area is then calculated by;

Area = 0.5 * Products of two sides (other than the hypotenuse)

Area = 0.5 * 8cm * 6cm

Area = 24cm^2

<u>For Prism B</u>

Lengths = 5cm\ and\ 5cm

So, the area is:

Area = 5cm * 5cm

Area = 25cm^2

<em>By comparison, prism B has a larger base area because </em>25cm^2 > 24cm^2<em></em>
