Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches
Equation is:
(q + 1 ) / 16= 4
For q:
Multiply 4*16
q + 1 = 64
Subtract 1
64-1=63
q = 63
Answer:
C
Step-by-step explanation:
∠CDE = 0.5( mEC - m CE )
The arcs CE and EC must add to 360°, thus
arc EC = 360° - 105° = 255°, hence
∠CDE = 0.5(255 - 105)° = 0.5 × 150° = 75° → C
1000 millimeters = 100 centimeters
