Question

PLEASE HELP ME WITH THIS!!

Answer 1

Answer:

86.9 cm squared

Step-by-step explanation:

The surface area of a rectangular prism is denoted by: $A=2lw+2lh+2wh$, where l is the length, w is the width, and h is the height.

Here, the length is l = 5.3, the width is w = 2, and the height is h = 4.5. So, plug in these values:

$A=2lw+2lh+2wh=2*5.3*2+2*5.3*4.5+2*2*4.5=86.9$

Thus, the surface area is 86.9 cm squared.

Hope this helps!

Answer 2

Answer:

86.9 cm^2

Step-by-step explanation:

A=2(wl+hl+hw)

A=2(2*5.3+4.5*5.3+4.5*2)
