Let's find area of the base.: 5x4.3=21.5, 21.5/2=10.75
Area of the Faces : 5x3=15/2=7.5x4=30
Let's add 10.75 +30=40.75
You can plug 1350 or less watts without overloading the circuit.
Step-by-step explanation:
Given,
Circuit overloads at = 2400 watts
Electricity consumed by portable heater = 1050 watts
Let,
x be the additional number of watts you can plug in.
Portable heater + additional watts ≤ Overloading limit
1050 + x ≤ 2400
Subtracting 1050 from both sides

You can plug 1350 or less watts without overloading the circuit.
