Answer:
1.) 167.2cm^3 2.) 30.96cm^3
Step-by-step explanation:
V = lwh
= (5.0cm)(4.4cm)(7.6cm)
= 167.2cm^3
V = lwh
= (1.5cm)(2.4cm)(8.6cm)
= 30.96cm^3
Make sure to cube your units on the final answer, and the brackets mean you're multiplying.

Answer:
Each dimension increased by 3 ft.
Step-by-step explanation:
Area of the original rectangle = 4 * 6 = 24 square feet
Increased dimension = x ft
New length = 6 + x
New width = 4 +x
New area = (6 + x)(4 +x) {Use FOIL method}
= 6*4 + 6*x + x*4 + x*x
= 24 + 6x + 4x + x²
= x² + 10x + 24
New area = 24 + 39
x² + 10x + 24 = 63
x² +10x + 24 - 63 = 0
x² + 10x - 39 = 0
x² + 13x - 3x - 3*13 = 0
x (x + 13) - 3(x + 13) = 0
(x + 13)(x -3) = 0 {Ignore x + 13, as it gives negative value}
x - 3 = 0
x = 3
