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?

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

Therefore, the surface area is equivalent to

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
