Let's name the number 'n'. Now write an equation. 7*n +n^2 =12Now you can form a quadratic. n^2 +7n-12=0. Now you can use a myriad of methods to solve it. If you still need help, just message me.
Answer: 52 square cm
Step-by-step explanation:
The given surface area formula of a rectangular prism,
S = 2 wl + 2 lh + 2 hw
Where is the length, w is the width and h is the height of the prism,
Here, length, l = 2 cm,
Width, w = 3 cm
And, Height, h = 4 cm
Thus,The required surface area of the prism,
S = 2 × 3 × 2 + 2 × 2 × 4 + 2 × 4 × 3
S = 12 + 16 + 24 = 52 square cm.
Volume of cylinder =Π r^2 h
where 'r' refers to radius and 'h' refers to height of the cylinder
volume of cylinder = Π (2)^2 (6)
= Π (4)(6)
=Π (24)
75.36 cm^3 is the volume of the cylinder.
