length= 13cm, width= 10.8cm, height= 3cm

Question

A. Zara is learning about surface area and volume in math class. She begins to notice that she can apply this geometry in everyday life. When her mom makes a jelly sandwich for her lunch, Zara notices it is similar to a rectangular prism and decides to measure its dimensions. She measures the length as 13 cm, the width as 10.8 cm, and the height as 3 cm, as shown below.

Answer 1

V = 13x10.8x3 = 421.2 cm^3

A = 2(wl + wh + lh) = 2(140.4 + 32.4 + 39) = 2(211.8) = 423.6 cm^2
