Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.
Hope it helps!
D. Is the one which has slope -3
It is because the point of it’s slopes are
( 0,0) and (1,-3)
So the slope will be
(Y2 - Y1)/(X2-X1)
Hence -3 is the slope of graph D.
Answer:
13 miles
Step-by-step explanation:
The mid- segment is one half the size of the third side of the triangle, thus
distance across lake = 2 × 6.5 = 13 miles
The size of the sample space is 6*4=24.
Out of this, the outcomes that add up to 6 or higher are
1+5,6
2+4,5,6
3+3,4,5,6
4+2,3,4,5,6
for a total of 14 out of a sample space size of 24.
Therefore the probability is 14/24=7/12.
