Answer:
40 in²
Step-by-step explanation:
Surface area = 4 triangles + square
= 4[½ × 4 × 3] + 4²
= 4(6) + 16
= 40 in²

Answer:
96
Step-by-step explanation:
The least common denominator or lowest common denominator is the smallest multiple that the denominator (that is the number on the bottom of a fraction) has in common.
Since 32, and 3 have no common factors, one simply has to multiply them to find the least common denominator.
32 * 3 = 96
The correct question is;
Layla wants to build a wooden box with a volume of 45 cubic centimeters. She started with a width of 3 cm and a height of 3 cm. How long should Layla make the box?
Answer:
Box is 5 cm long.
Step-by-step explanation:
We are given;
Volume; V = 45 cm³
Width; w = 3 cm
Height;h = 3 cm
Now, this box has the shape of a cuboid and the volume of a cuboid is given as;
V = l × w × h
Where;
L is length
w is width
h is height
Making L the subject, we have;
V/wh = L
Plugging in the relevant values to obtain;
L = 45/(3 × 3)
L = 45/9
L = 5 cm
