Question

find the surface area of the prism using the net. what is the area of the front and back rectangles? front and back rectangles: ? cm² side rectangles: cm top and bottom rectangles: cm surface area: cm

Explanation:

Step1: Recall area formula for rectangle

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Identify dimensions of front - back rectangles

For the front and back rectangles, the length $l = 6$ cm and the width $w=4$ cm.

Step3: Calculate area of front - back rectangles

$A = 6\times4=24$ $cm^{2}$. Since there are 2 (front and back), the total area of front and back rectangles is $2\times24 = 48$ $cm^{2}$.

Answer:

48
