Question

the total surface area of a box is 300 sq m. if the length and height are 9m and 6m,respectively , find the breadth of the box.​

Answer 1

Step-by-step explanation:

total total surface area rectangle = 2(lb+bh+lh)

300. = 2(9b+6b+9×6)

300 =. 2(15b+ 54)

300= 30b + 108

300-108= 30b

192= 30b

b= 192÷30

b = 6.4 m

breath of the box is 6.4 m

Answer 2
