Answer:
<h2>1544 m³</h2>
Step-by-step explanation:
surface area = 2 × base + lateral area
base = (10×20)÷2 = 100
Lateral area = perimeter × height
= (20+14+14)×28
=1 344
Final answer :
surface area = 2 × base + lateral area
= 2 × 100 + 1344
= 200 + 1344
= 1544
42.6℅ of 230
=(426/10)℅ of 230
=(426×230)/1000
=97980/1000
=97.980
=97.98
Answer:
-21
Step-by-step explanation:
x3-3y
putting values in the equation
(-3)(3)-3(4)
-9-12
since the sign is minus - and - both are added but the answer will remain in minus
-21
