Alrighty
3 cubes
if you stack them then you can cover, at most 3 faces
each cube has 6 faces
so 6*3=18
minus the 3 coverd is 18-3=15
so if the surfece area is equal to 15 of those faces ten
84=15 faces
divide by 15
84/15=area of 1 face
a cube has 6 faces to multiply by 6
84/15 times 6=504/15=168/5=33.6 square inches is the surface area of one of grogg's cubes
Answer:
>90°
degrees from below 90 degrees
Answer:
t = 17.5
f = 12
Step-by-step explanation:
interior corner angles in a square = 90 degrees
4t + 20 = 90
4t = 90 - 20
4t = 70
t = 17.5
7f + 6 = 90
7f = 90 - 6
7f = 84
f = 12
Answer:
hence triangle can be formed with sides 5, 6,10
Step-by-step explanation:
it is fundamental principle of elementary geometry that sum of ant two sides of a triangle must be greater than the third side
here 5+6 is greater than 10
5+10 is greater than 6
6+10 is greater than 5
hence triangle can be formed with sides 5, 6,10
