Question

Total area= Help me please;! Asap thanks so much

Answer 1

The total area of the square based prism is 413.7 square units

How to determine the surface area?

The given parameters are:

Base length, a = 10

Height, h = 11

The total surface area is calculated as:

$A = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2$

This gives

$A = 10^2 + 2 *10\sqrt{\frac{10^2}{4}+11^2$

So, we have:

$A = 100 + 20\sqrt{246$

Evaluate

A = 413.7

Hence, the total area of the square based prism is 413.7 square units
