Question

Can you please help me with this

Answer 1

Answer:

-The total area of a Rectangular Prism:

$A = 366$ $in^{2}$

Step-by-step explanation:

-To find the total area of a rectangular prism, you need this formula:

$A = 2(l \cdot w + l \cdot h + w \cdot h)$

$l =$ Length

$w =$ Width

$h =$ Height

-Apply the length, width and height for the formula:

$A = 2(11 \cdot 8 + 11 \cdot 5 + 8 \cdot 5)$

$l =$ 11 in

$w =$ 8 in

$h =$ 5 in

-Then, solve for the area:

$A = 2(11 \cdot 8 + 11 \cdot 5 + 8 \cdot 5)$

$A = 2(88 + 55 + 40)$

$A = 2(143 + 40)$

$A = 2 \times 183$

$A = 366$

So, the total area would be $366$ $in ^{2}$.
