9514 1404 393
Answer:
486 square units
Step-by-step explanation:
Use the surface area formula with the given numbers.
SA = 2(LW +H(L +W))
SA = 2(12·6 +9.5(12 +6)) = 2(72 +9.5(18)) = 486
The surface area of the box is 486 square units.
Answer:
4.9x10^4
Step-by-step explanation:
4.9*10000=49,000
Part b is $638.40
Part c is $1,641.6
Answer:
<em>x = y = 64° , z = 20°</em>
Step-by-step explanation:
<em>x = y</em> =
<em>= 64 </em>°
m∠ADC = 52° + x
m∠ADC = 52° + 64° = 116°
<em>z</em> = 180° - 116° - 44° <em>= 20</em> °
