Answer:
a) 184cm³ b) 15.3cm³
Step-by-step explanation:
A) Vol. of block of cheese= L×B×H= 8cm×4cm×6cm= 192cm³
Piece of cheese cut out= S×S×S= 2cm×2cm×2cm= 8cm³
Remainder= 192cm³ - 8cm³ = 184cm³
B) Remainder = 184cm³ is cut into 12 equal pieces
Each pieces = 184cm³ ÷ 12 = 15.3cm³
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same
This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6
D = r x t
40= r x 1
40/1 = r x 1/1
r = 40 mph
rate = distance/time
