Question

A rectangular brick has dimensions of 5.7 centimeters by
9.5 centimeters by 20.3 centimeters. What is the surface area of
that brick?

Answer 1

Answer:

$725.42 cm^{2}$

Step-by-step explanation:

Surface area will be SA=2(lw+lh+wh) where l represent length, w represent width and h represent height

Given information

Length, l=20.3 cm

Width, w=9.5 cm

Height, h=5.7 cm

Substituting the above then surface area will be

$SA=2(20.3*9.5+ 20.3*5.7+ 5.7*9.5)=725.42 cm^{2}$

Therefore, the surface area is equivalent to $725.42 cm^{2}$
