Answer:
The perimeter of a face of the new cube is:
108 cm
Step-by-step explanation:
Original edge length of cube=9 cm
Increased edge length of the cube=9×3 cm
=27 cm
The perimeter of a face of a cube=4s
where s is the edge length of the cube
Perimeter of a face of new cube=4×27 cm
= 108 cm
Hence, the perimeter of a face of the new cube is:
56 + 24 = 80
56 X 100 = 5600
5600/80 = 70%
3x^2
3x^2 can be factored out of each
-6x^2 = 3x^2(-2)
21x^3 = 3x^2(7x)
-0.28
(-6)-(-8)=2.
7-14=-7
2/-7=-0.28
208 ⅓ ft²
1⅞ = 15/8 inches ÷ 12
= 5/32 feet on map
Actual = 5/32 × 80
= 25/2 feet
2½ = 5/2 inches ÷ 12
= 5/24 feet on map
Actual = 5/24 × 80 = 50/3
Actual area:
25/2 × 50/3
= 625/3 ft²
= 208 ⅓ ft²
