I believe the answer is 25 but I could be very wrong.
Explanation:
a^2(t)+b^2=c^2
a^2(t)+12^2=13^2
a^2(t)+144=169
-144 -144
a^2(t)= 25
25^2= 625
The square root of 625 = 25
t=25

Step-by-step explanation:

By Pythagoras' Theorem,

t² = 13² - 12²

=> t² = 169 - 144 = 25

=> t = 5 (as t is non-negative).

Cade covered the outside of a box shaped like a rectangular prism with paper. The box is 3.5 feet long, 2.2 feet wide, and 4.1 f

Orlov [11]

Answer:

The total surface area of this box is 62.14 square feet

Step-by-step explanation:

Given:

Length = 3.5 feet

Width = 2.2 feet

Height = 4.1 feet

To Find:

The Surface area of the prism = ?

Solution:

The box is the shape of rectangular prism

Then the surface area of the prism = 2(lh +hw +wl)

Where

l is the length

w is the width

h is the height

Substituting the values

The surface area of the prism = $2((3.5 \times 4.1) +(4.1\times + 2.2) +(2.2 \times 3.5))$

The surface area of the prism = 2(14.35 + 9.02 + 7.7)

The surface area of the prism = 2(31.07)

The surface area of the prism = 62.14 square feet
