Ans
184 sq meter
Step-by-step explanation:
Area of the cuboid box = (2*FA)+(2*SA)+(2*TA)
Where FA= Front face area
SA= Side face area
TA= top face are
Here FA= length * breadth = 10*6=60 sq meter
SA= 10*2= 20 sq meter
TA= 6*2= 12 sq meter
So area of box= 2*60+2*20+2*12= 184 sq meter
Hello!
(7x²y³)(3x⁵y⁸)
Multiply by ADDING exponents with the same base:
(7 * 3) (x² * x⁵) (y³ * y⁸)
21 * x² ⁺ ⁵ * y³ ⁺ ⁸
Simplify:
21 * x⁷ * y¹¹
21x⁷y¹¹
Answer:
17 /6 t
Step-by-step explanation:
3t2+4t3
=32t+43t
Combine Like Terms:
=32t+43t
=(32t+43t)
=176t
that would mean he's 7 right now
