Answer:
128
Step-by-step explanation:
x³y²if x = 2 and y = 4
x³*y²

(2*2*2)*(4*4)
(8)*(16)
128
Answer:
The perimeter before is 5+4+5+4=18.
After doubling the length, we do 10+4+10+4=28.
The difference is 10, so the perimeter increases by 10.
Answer:
Volume = = 138⁶/32 cubic meters
Step-by-step explanation:
Given:
Length = 8⅜ m
Width = 2 m
Height = 8¼ m
Required:
Volume as a mixed number
Solution:
Volume of rectangular prism = L*W*H
Plug in the values
V = 8⅜ × 2 × 8¼
Change to improper fraction
V = 67/8 × 2 × 33/4
= (67 × 2 × 33)/(8 × 4)
= 4,422/32
= 138⁶/32 m³
