?
Step-by-step explanation:
Bruce's dumbbells weigh 11 pounds each
Bruce has 14 dumbbells
we know that to calculate the total weigh of all the dumbbells we have to multiply weigh of each dumbbell with the total no of dumbbells
this is because by multiplying the no of dumbbells with weight of each one we get the altogether weight
so we will multiply weight of each dumbbell by total no. of dumbbells
by multiplying we get 14*11=156
therefore the altogether weight of dumbbells is 156 pounds.
