Question

1. calcule laire latérale de ce solide. identifie correctement où se trouve les bases! **rappel: quelle est la définition de la hauteur dun solide? largeur = 7 cm, profondeur = 13 cm et h = 2 cm

Explanation:

Step1: Recall lateral - area formula for rectangular prism

The lateral - area $L$ of a rectangular prism is given by $L = 2h(l + w)$, where $h$ is the height, $l$ is the length, and $w$ is the width. Here, assume length $l = 13$ cm, width $w = 7$ cm, and height $h = 2$ cm.

Step2: Substitute values into the formula

$L=2\times2\times(13 + 7)$.
First, calculate the sum inside the parentheses: $13+7 = 20$.
Then, $2\times2\times20=80$ $cm^{2}$.

Answer:

$80$ $cm^{2}$
